RetroFitting Adaptive Cruise Control - Possible on Q7 so in theory.....

• Add to quote

I've been cruising (no pun intended!) around the wonderous www today and found this thread. Adaptive Cruise Control (ACC) Retrofit | Audi Forum It shows this guy managing to retrofit ACC to his Q7. I've always said (apart from cost of parts etc) that to do this you need a new instrument cluster, but it seems he didnt change his and it still worked. I'm not saying by any means the same rules may/may not apply to the A5/S5 range but if its do-able in a Q7 it may mean its more possible than you think in a A5/S5.. Just my 2p... Cheers Andy  

I don't like the big cyclops eye on the front myself.

ACC (Adaptive cruise control Retrofit)

OK guys for those of you wishing to carry out the above this will hopefully give you the info required to help you on the way.

On the face of it it seems like a big job but when its broken down into sections it really is not that bad to do.

So I went about the job by first trawling through ELSA, ETKA and Bentley manuals to see what parts are needed to complete.

The key components to working ACC are (Note the S8 related parts)

[ ]S8 Instrument Cluster 4E0 920 981 FX [ ]Distance regulation control stalk 4E0 953 521 C 4PK [ ]Gateway with extended CAN 4E0 907 468 F or 4E0 907 468 H [ ]Radar unit 4E0 907 561 F [ ]Plug housing for radar 4E0 972 713 [ ]Terminals for radar Plug housing can be found here [ ]Plug seals for housing here [ ]Wire seals for housing here [ ]S8 Grill suitable for ACC 4E0 853 651 AM 1RR Grill comes with no number plate surround or fasteners but does include radar cover. [ ]licence plate holder 4E0 807 285 AD 1RR [ ]4 x Panel Screws N 104 055 02 [ ]4 x Speed Nuts N 900 942 01 [ ]1 x Repair wire for Gateway extra wiring 000 979 010 E [ ]1 x Repair wire for Mini Fuse fitment 000 979 021 E [*]3 x M6 x 16mm bolts for mounting radar N 104 492 02 (Specially coated to prevent corrosion don’t cheap out and use normal ones)

You will also need to source the following if you don’t have it already

Before starting work do a full Auto scan and be sure to save the results.

I recommend you have at least a radar, gateway, and the parts for wiring that are needed so you can test the radar before removing the bumper etc and having a disappointment.

Begin by making a harness for the radar to the Gateway and fuse box, I made mine starting at the Radar end so it would be an unbroken loom without joints on the outside of the car.

Pace out the length needed from front centre, across the front to passenger headlight, over the top of the wing and onwards to the inside giving yourself plenty extra so you can terminate inside the car.

Using two separate coloured wires mount them in a drill and fasten other ends in vice or have assistant help, twist the wires together to form a twisted pair of fairly tight lay up <20mm

http://forum.a8parts.co.uk/attachment.php?attachmentid=11623&stc=1&d=1439560231

Insert the terminals in the housing after unlocking the pink locking strips by pushing them across the housing, with the locking tang facing outwards of the housing until you feel it snap into place.

Do not push in the wire seals yet!!!

Once you have done that check the continuity of the harness with a multimeter by back probing the housing before proceeding any further, once happy tape the harness together using the coroplast tape. (Sorry no pictures)

Still don’t insert the seals yet!!!

The wire numbers and my colours are as follows

1-Ground (Blue) 2-Can-H (Orange) 4-Can-L (Yellow) 12-!2v Positive feed (Red)

http://forum.a8parts.co.uk/attachment.php?attachmentid=11625&stc=1&d=1439560409

This is the wiring diagram

http://forum.a8parts.co.uk/attachment.php?attachmentid=11640&stc=1&d=1439567880

Next would be the replacement of the Gateway and inserting extra wires to gateway harness and test the radar.

The Gateway is at the heart of the system changing it will not create any problems with the car while you are using it prior to fitting the other parts, you will however get a fault logged saying there is no comms with radar which is to be expected.

I am of the understanding that the Q7 gateways can be used in the A8/S8 but there is a chance that Component Protection will kick in if fitted.

I chose to stick to A8/S8 part numbers that were relevant to the systems I wanted in the car and I did not encounter CP on the fitment of the Gateway.

To gain access to the Gateway it requires the removal of the glovebox

You can take a little shortcut here like I did and drop the glovebox with the AMI/CD changer still in it or take them out like in the photo’s below.

I also find it easier if you remove the sill trim, pull it up nearest the seat and work forward and finally pull it away from dash.

http://forum.a8parts.co.uk/attachment.php?attachmentid=7829&d=1397685059

So in the centre of the last picture above you can see the gateway next to the control head for the mmi

Replacement is really a matter of unclip the two connectors one electrical and one optical and two torx bolts.

While you are in here its a good time to prep the Gateway harness to accept the wiring from the radar and also to test the radar.

Start by sliding the locking tab on the end of the removed gateway electrical connector housing and then sliding out the internal part with the wires in.

Cut the repair wire 000 979 010 E in half and insert into 13 and 26 like the pictures below, mark the one in 13 with a sharpie pen or something so you know which one is CAN-H, then twist together.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11627&stc=1&d=1439562667

http://forum.a8parts.co.uk/attachment.php?attachmentid=11628&stc=1&d=1439562116

http://forum.a8parts.co.uk/attachment.php?attachmentid=11629&stc=1&d=1439562116

Now temporarily join the pin 13 gateway to pin 2 radar, and 26 to 4 using choc block or similar and check again for correct connection and continuity.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11630&stc=1&d=1439562714

Once you are happy you have wired the CAN connections correctly, connect the gateway harness back together and code the gateway to suit the options on your car (easy way is to copy the coding from your VCDS scan that you took prior to starting this, then using the long coding helper add ACC as well.

Also code module 7 for ACC

Once happy connect the radar to a fused supply, I used a cigar lighter adaptor connection thing and temp wired it to that.

Then you should now have the extra menu appear in the MMI under car/systems/adaptive cruise control

This is a quick visual way to tell you have comms with the radar, the other way is with vcds and look for module (13)

http://forum.a8parts.co.uk/attachment.php?attachmentid=11631&stc=1&d=1439564633

http://forum.a8parts.co.uk/attachment.php?attachmentid=11632&stc=1&d=1439564633

Now you can inserts the seals and plugs into the Connector housing for the radar.

Now you need to prep the fuse box for the connections that feed the radar or you could do this first before testing the radar, either way.

You need to remove the two bolts that hold the passenger side fuse box in place from the end of the dash and unclip the fuse box from the dash frame.

The pics are the opposite side but the same applies.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11633&stc=1&d=1439565955

http://forum.a8parts.co.uk/attachment.php?attachmentid=11634&stc=1&d=1439565404

Now open the back of the fuse box and release the pink locking bar by sliding it over, so you may insert the fuse terminal repair wires 000 979 021 E into both side of slot 17

http://forum.a8parts.co.uk/attachment.php?attachmentid=11639&stc=1&d=1439565763

Locking bar in locked position

http://forum.a8parts.co.uk/attachment.php?attachmentid=11636&stc=1&d=1439565654

Lever point to open the locking bar

http://forum.a8parts.co.uk/attachment.php?attachmentid=11635&stc=1&d=1439565654

Locking bar in open postion

http://forum.a8parts.co.uk/attachment.php?attachmentid=11637&stc=1&d=1439565654

Yellow repair wire inserted

http://forum.a8parts.co.uk/attachment.php?attachmentid=11638&stc=1&d=1439565654

Now I apologise I have no pictures of the connections in the back of the fuse box because I was pushed for time that day.

However you will see when you open the passenger side fuse box that slot 17 has no terminals so yo must fit both, using the repair wire cut in half, fit both terminals and lock the bar once done.

If you look at the wiring in the fuse box there is a few solid black wires, choose one of the wires and cut it in a suitable place to allow you to splice in the repair wire and join both sides of the black wire together using solder and heat-shrink or a butt crimp if you don’t like soldering but I prefer solder over crimps.

The reason for using the black wire is it is a switched live and is only on with ignition on. Study the electrical diagrams and you will see the radar is also fed from a black wire which originates from the same relay.

Now once you have done that and happy the unterminated wire ends from gateway are going to come to no trouble you can put the glovebox back together for a while like I did or continue with the bumper removal and fitment of radar.

To fit the radar, the bumper needs to be removed along with the passenger side wheel arch liners and wheel, if you have axle stands or access to a ramp you may as well go ahead and remove the drivers side wheel too just to make life easier.

The instructions here are a bit vague IMO and I really struggled first time round on the bumper removal, so tips from me are

[ ]Pull out the foglight cover drivers side and remove the fog light [ ]Disconnect the headlight washer pipe from the t piece carefully [ ]Remove the fixings around the bottom of the wing [ ]Drop the belly pan away from rear edge of bumper [ ]Remove the front half of wheel arch liner completely on passenger side [ ]Peel back the drivers side arch liner enough for access to the three nuts holding the bumper to the wing [ ]Remove the three nuts both sides [ ]Pull out the black trim that runs along the top of the grill [ ]Dig out the two pieces of sponge hiding two bolts [ ]pull out both side of the bumper at the bottom of the wings [*]Finally remove the fixings along the top of the bumper 7 in total

You can now carefully pull bumper clear of the car and be careful as there are two electrical connectors attached to the bumper on passenger side, release them and you should be clear to put it to one side.

You can reach the three nuts securing the bumper to the wing (driver side) by reaching around through the opening but its easier through the wheel arch with liner peeled back.

You can see the studs where the three nuts are and the washer hose t piece in this photo

http://forum.a8parts.co.uk/attachment.php?attachmentid=11641&stc=1&d=1439572047

With the bumper off you can now continue and peel back the rear wheel arch liner on the passenger side to reveal the route in for the wiring.

This shows the rear liner pulled down enough for clearance

http://forum.a8parts.co.uk/attachment.php?attachmentid=11642&stc=1&d=1439572467

Now go ahead and mount the Radar to the bumper beam, it can be done with it in place but for all the time it took to remove it, I chose to do it that way.

Its just two 18mm bolts either end and remove the horn bracket from the mounting giving you easy access to the three mounting holes for the radar bracket.

Mounted to bar and cable following existing wiring

http://forum.a8parts.co.uk/attachment.php?attachmentid=11648&stc=1&d=1439572467

Harness follows the original wiring past headlight like below see white tyraps for route

http://forum.a8parts.co.uk/attachment.php?attachmentid=11646&stc=1&d=1439572467

http://forum.a8parts.co.uk/attachment.php?attachmentid=11647&stc=1&d=1439572467

The harness continues through into area at the top of the wing and follows the original wiring back to the rear of the wing next to the Valve block for the Suspension.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11645&stc=1&d=1439572467

http://forum.a8parts.co.uk/attachment.php?attachmentid=11643&stc=1&d=1439572467

Once you have reached the area of the Valve block you need to release the metal clamp holding the loom in place and cut off the tyrap around the neck of the rubber boot.

Then using a coat hanger or cable fishing device feed the harness from one side of the rubber boot to the other side inside the car.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11644&stc=1&d=1439572467

You can see the new harness inside the rubber boot now.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11649&stc=1&d=1439573216

Refit the cable clamp to the loom and you can now go ahead and finish the wiring for the radar inside the car.

Cut back the harness to a sensible length now and remove the loom tape far enough back to allow you to join the required wires together.

You will have already put in the repair wires to the fuse box, so go ahead and solder or crimp them together and insulate

Join the two can wires in the same way to the tails you have from before ensuring to keep the twist as tight as possible to avoid interference.

Fit the ground wire crimp and bolt to the chassis of the car just inside the door at the base of the pillar.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11653&stc=1&d=1439574795

Only hardware items remaining are the stalk for cruise control and the cluster.

To remove the stalk the Steering wheel needs to be removed.

But in order to do so the Airbag needs to be removed and its easier done with the engine running.

Start the car and rotate the wheel round 90 degrees and remove the cap covering the securing bolt for the airbag, turn to the opposite way and repeat, make sure once you have undone the bolts to prevent the airbag falling out of the wheel while you re-centre the steering.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11662&stc=1&d=1439634518

Now Disconnect the battery with the ignition on but not with engine running to dissipate energy from the electrical systems and prior to unplugging the airbag be sure to ground yourself first by touching the door latch loop or other point of chassis.

Pull the airbag forward carefully and disconnect the wiring harness and put aside, remove the securing bolt from the centre and mark the alignment of the wheel then remove it.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11663&stc=1&d=1439634815

http://forum.a8parts.co.uk/attachment.php?attachmentid=11664&stc=1&d=1439634815

http://forum.a8parts.co.uk/attachment.php?attachmentid=11665&stc=1&d=1439634815

You need to drop the dash below the steering wheel and to do that remove the trim both sides like in the pictures.

Start by opening the coin holder the slide the front part to the left so it unclips, then close it again.

You can now remove the trim piece by starting at the end nearest the door pry outward with a trim tool working along towards the steering wheel.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11657&stc=1&d=1439633903

http://forum.a8parts.co.uk/attachment.php?attachmentid=11658&stc=1&d=1439633903

Do the same process for the short trim on the other side

http://forum.a8parts.co.uk/attachment.php?attachmentid=11659&stc=1&d=1439633903

Now remove the fasteners for the lower dash panel, one either side of column, two on end of dash at fuse box and one next to transmission tunnel, carefully lower the panel and disconnect the various plugs

http://forum.a8parts.co.uk/attachment.php?attachmentid=11661&stc=1&d=1439635412

To remove the shroud from the column you will need a T8 torx screwdriver, for two of the screws as its quite a deep recess and I had to shave the handle down on the one I have for it too reach.

The cover comes apart in a swinging motion as it kind of hinges from the back.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11668&stc=1&d=1439643655

Once you have released the electrical connections of the module, slacken the clamping screw on the underside to release the steering module with the slip-ring and stalks on and slide it off the column.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11671&stc=1&d=1439644020

http://forum.a8parts.co.uk/attachment.php?attachmentid=11670&stc=1&d=1439644020

http://forum.a8parts.co.uk/attachment.php?attachmentid=11669&stc=1&d=1439644020

I advise you to tape the slip ring or be careful not to let it turn, you don’t want to fit it back on one revolution out of place and damage it.

If like me you purchased the stalk only then you will need to remove the slip-ring from the rest of the module, do so by releasing the tabs and sliding the unit off.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11672&stc=1&d=1439644514

http://forum.a8parts.co.uk/attachment.php?attachmentid=11673&stc=1&d=1439644514

http://forum.a8parts.co.uk/attachment.php?attachmentid=11675&stc=1&d=1439644514

Now to remove the stalk from the module remove the securing screws (T8) from both the cruise stalk and the indicator stalk, then using your finger placed like mine in the picture you can gently pull down the part where the cruise stalk plugs in to get it free.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11676&stc=1&d=1439644891

http://forum.a8parts.co.uk/attachment.php?attachmentid=11677&stc=1&d=1439644891

Now for your new stalk, rebuild the module and slip ring and refit to the column, replace shroud and steering wheel.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11678&stc=1&d=1439644891

http://forum.a8parts.co.uk/attachment.php?attachmentid=11679&stc=1&d=1439646272

Now from here I rebuilt the car as I had an appointment the following week to have the cluster done, the dealer wanted the old cluster in upon arrival so they could copy settings and mileage across to the new cluster.

In order to keep the costs down I had agreed with the service advisor that I would prepare the car so all they had to do was copy the info and unplug the old cluster and pop in the new one and transfer the details across.

The charge for that was 30mins labour at £60

The trim around the instrument cluster is fairly easy to remove and I did it sitting in the car park of Audi prior to the appointment.

To do so remove the aluminium trim as before in this thread both sides of the dash Remove the air vents either side of the cluster using Marcins guide as follows

There are two locking clips on each vent, use a thick ish, not to flexible, steel wire bend in U shape or use two very small allen keys. Lift the clips and pull the vent out but be carefull as there is a electrical connector on each vent.

http://forum.a8parts.co.uk/attachment.php?attachmentid=10838&stc=1&d=1432571506

Next undo the hex bolts as per pictures below

http://forum.a8parts.co.uk/attachment.php?attachmentid=10839&stc=1&d=1432571506

http://forum.a8parts.co.uk/attachment.php?attachmentid=10840&stc=1&d=1432571506

And to remove the trim

• lower and extend out the steering wheel as far as possible
• turn the ignition off, left, but leave the key to stop the steering wheel going into exit position (up)
• indicator lever down
• hold wipers lever down while removing the trim
• rotate the trim from the bottom out as if hinged at the top

Once you have the cluster in and CP removed you will need to carry out the coding on the various modules required.

The Gateway uses long coding, Open module 19-CAN Gateway click on “long coding helper” In the popup window, using the down arrow on the keyboard press it enough times until you are at byte 4, then check the bit 0 box for [13] Distance Regulation. Press the escape key, that will copy the new coding to the new coding box Press Do it!

http://forum.a8parts.co.uk/attachment.php?attachmentid=11680&stc=1&d=1439652648

The Control head [07] has to be adapted to have the adaptive cruise control menu in systems on the mmi

Open the module 07-Control Head and press adaptation button, then from the drop down choose Installation list 1 then hover you mouse over the value box and the helper pop up will appear like below, using it add 1 to the stored value, press test then save and close the controller.

http://forum.a8parts.co.uk/attachment.php?attachmentid=11681&stc=1&d=1439652648

Module 1 Engine I and 11-Engine II need the same coding change Click on Long coding helper In the popup window, using the down arrow on the keyboard press it enough times until you are at byte 6, then uncheck the bit 0 box and check bit box 1 The value for byte 6 should be 02 like in the pic below. Press the escape key, that will copy the new coding to the new coding box Press Do it!

Remember the same process for 11-Engine II

http://forum.a8parts.co.uk/attachment.php?attachmentid=11682&stc=1&d=1439652648

Open module 13-Auto Dist. Reg, CONTROLLER 13 Autodistance radar sensor controller has to be coded following this label: Position 1: Engine coding 1XXXX: 8-cylinder (4.2-litre petrol engine and 4.0-litre TDI engine and 4.2-litre TDI and 4.2-litre FSI) 2XXXX: 8-cylinder (3.7 litre petrol) 3XXXX: 6-cylinder MPI (3.0 litre with Multitronic gearbox “01J”) and 6-cylinder TDI (3.0 litre with 6-speed gearbox “09L”) and 6-cylinder FSI (3.2 litre with Multitronic gearbox “01J”) and 6-cylinder FSI (2.8 litre AVS with Multitronic gearbox “01J”) 4XXXX: 12-cylinder 6.0 litre petrol engine and 10-cylinder FSI 5.2 litre petrol engine Position 2: Country coding 1 A 1 is always entered at this position Position 3: Body coding XX1XX: Standard body XX2XX: Stretched body Note on position 3: This coding adapts the vehicle mass and wheelbase accordingly. Position 4: Country coding 2 XXX1X: USA (mph) XXX2X: Canada (km/h) XXX3X: ---------------------------- XXX4X: Japan XXX5X: RoW (mph) (RoW = Rest of the World) XXX6X: RoW (km/h) Position 5: Optional extras (added together) XXXX1: Vehicle with trailer hitch and/or Rear Seat Entertainment system fitted- If one or both of the systems is/are fitted, the adaption value is always 1!! XXXX4: Vehicle with one-touch memory XXXX8: Without optional extras If no optional extras are coded, the coding value 8 is entered

Open module 16-Steering wheel Click on coding and change the second last digit to the appropriate value in my case it went from 4 to 5

http://forum.a8parts.co.uk/attachment.php?attachmentid=11683&stc=1&d=1439652648

Open module 17-Instruments click on security and login with the code 13861 to enable adaption of the module

http://forum.a8parts.co.uk/attachment.php?attachmentid=11684&stc=1&d=1439652648

Then click on adaptation and select Adaptive cruise control from the drop down Enter a new value of 1, test, save and close controller

http://forum.a8parts.co.uk/attachment.php?attachmentid=11685&stc=1&d=1439652648

At this point switch of the ignition and go have a cuppa.

The instrument cluster and possibly the other module need to be power cycled before the adaptions and coding become active, this led me to much frustration because I didn’t do it when adapting the new cluster and it didn’t behave as expected.

Now if at this point you have connected everything back up and fitted all the trims do a full scan, clear any faults and scan again to see if you have any problems you should have a operational system at this point.

Only thing left to do is drive it and see if it works and possibly to some fiddling with basic settings of the radar.

Unfortunately the radar has no label files so, but you can download the attached text file and save it into the User folder of your ross tech labels folder, then re-save the file with the ext .lbl and have the various measuring blocks you need when you open VCDS.

The picture below is of the measuring blocks that are of importance

http://forum.a8parts.co.uk/attachment.php?attachmentid=11747&stc=1&d=1440525359

Group 002 block1 is horizontal alignment and block 2 is vertical alignment.

Group 11 block 1 is Steering angle sensor. and group 11 block 2 is lateral yaw rate offset.

According to elsa both the beam alignment angles have to be 0.5 degrees or less to function error free.

I had readings of over 2 degrees after a run, but on the next run out it was less, I think it relearns on every drive so the readings may be way off if you journey had a lot of bends in it.

To clear the values one must perform a basic setting to allow the radar to relearn the offsets.

Do this by selecting basic setting then press the go button next to 001 Then press the on/off/next button twice Then manual change the group value box to 002 and perform the same steps Repeat this process for 003 and 004 Press Done,Go back and close the controller Ignition off wait for a bit then go for a drive and see if it works.

I don’t think I have missed out anything important but if you want to ask questions then please do.

If your doing this to something other than an S8 then the coding/adaption for the engine could be different

I found this thread on retrofitting ACC very useful and it has info in there for coding the engine in cars with one ecu.

Lastly I would like to thank Dave @ A8 Parts for sorting me out the parts I needed +++

Guys Sorry but the copy and paste didn’t work properly and all the links have been fubar’d and until i get edit privileges I cant fix them.

If you want to read the thread where I originally posted it then you can find it here

Audi Q7: Using adaptive cruise assist

Applies to: vehicles with adaptive cruise assist

Switching on

• To switch on the adaptive cruise control, pull the lever up to position 1 until it engages.

Storing the speed and activating regulation

If you have switched the system on, you can set the current speed as the "regulated speed" and activate regulation:

• To save the speed while the vehicle is stationary, also hold the brake pedal down.

You can set any speed between 15 mph (20 km/h) 1) and the maximum possible speed range 3 2) , fig. 108.

1) Analog instrument cluster: 20 mph (30 km/h) 2) Depends on the country and engine

Pausing cruise control

The control can be stopped at any time:

• While driving or when the vehicle is stationary: Press the lever away from you in the direction of the arrow. Or
• While driving: Press the brake pedal.

Resuming regulation

The previously set speed can be resumed at any time after a pause.

• To resume cruise control while driving, pull the lever toward you in the direction of the arrow.
• To resume cruise control when stationary, pull the lever toward you in the direction of the arrow while pressing the brake pedal.

Changing the speed

• To increase or decrease the set speed in smaller increments, briefly tap the lever toward (+) or (0) to the first level.
• To increase or decrease the set speed in larger increments, briefly tap the lever toward (+) or (0) to the second level.
• To increase or decrease the set speed continuously, hold the lever toward (+) or (-) until the marking in the speedometer (1), fig. 108 has reached the desired speed.

Applies to: vehicles with predictive control: Predictive control can automatically adjust the set speed based on traffic and road conditions.

Preselecting a speed

You can also preselect the speed when adaptive cruise control is not active by moving the lever in the desired direction (+)/(-). Activate the previously selected speed by pulling the lever toward you in the direction of the arrow.

Switching off

If you do not want to use the adaptive cruise control for a long period of time, you can switch it off.

• Push the lever away from you into position (0) until it clicks into place.

The indicator light and the set speed will turn off.

• Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
• The activated adaptive cruise control is only an assist system, and the driver is still responsible for controlling the vehicle. The driver is especially responsible for braking, steering, starting to drive, and controlling the speed and the distance from other vehicles.
• Turn on the adaptive cruise control only if the surrounding conditions permit it. Always adapt your driving style to the current visual, weather, road, and traffic conditions.
• Switch adaptive cruise control off temporarily when driving in turning lanes, on expressway exits or in construction zones. This prevents the vehicle from accelerating to the stored speed when in these situations.
• If you press the [SET] button (2) when driving at speeds below 15 mph (20 km/h) 1) , the minimum possible speed that the system can maintain will be set. If no vehicle is detected ahead of you, the vehicle will accelerate up to that speed.
• Always keep your hands on the steering wheel so you can be ready to steer at any time. The driver is always responsible for adhering to the regulations applicable in the country where the vehicle is being operated.
• If you switch the ignition or the adaptive cruise control system off, the set speed is erased for safety reasons.
• When adaptive cruise control is switched on, the ESC and ASR automatically switch on.
• The system cannot be switched off or it may be interrupted if the road exceeds the maximum possible grade for safe operation.

Driver assistance systems

Share article

Audi assists drivers with a broad range of assistance systems – from turn and parking assistants to the camera-based road sign recognition. They deliver more safety, convenience and efficiency, and they pave the way for piloted driving.

We are currently revising our content. Please understand that we cannot provide you with the most up-to-date information on every topic at the current moment.

Turn assist

Turn assist monitors the road lane with oncoming traffic by means of radar sensors, the front camera and, in certain models, a laser scanner. Monitoring is initiated as soon as the driver sets the turn signal. When driving off from a stop, or during slow driving up to a speed of 10 km/h (6.2 mph) , the system can intervene by applying the brakes to prevent the car from colliding with an oncoming vehicle when turning left or right (country-dependent). This brake intervention keeps the vehicle within its own driving lane. The driver is informed of the intervention by an indicator in the instrument cluster.

Adaptive cruise control (with Stop&Go function)

Adaptive cruise control (ACC) offers relief to drivers especially on long trips and in stop-and-go traffic. It maintains a preset distance to the vehicle ahead by automatically accelerating and braking. The driver can choose from five distance levels and adjust acceleration and control system dynamics with Audi drive select.

The system uses radar sensors and a front camera. They detect vehicles ahead and measure the distance to them. In interplay with S tronic or tiptronic, the system covers the entire speed range from 0 to 250 km/h (155.3 mph) . With a manual transmission, it starts at 30 km/h (18.6 mph) . When the system is deactivated, the distance indicator shows the distance to the car ahead and warns drivers when they are tailgating. Its operating speed range is 60 km/h (37.3 mph) and above.

When combined with S tronic or tiptronic, ACC also includes the Stop&Go function. In heavy traffic, it autonomously decelerates the car to a stop. After a brief stop, it automatically resumes driving, following the vehicle ahead. After a longer stop, the driver must tap the accelerator pedal or the control stalk on the steering column. In addition to the radar sensors and front camera, ultrasonic sensors also monitor the vehicle’s immediate surroundings.

Adaptive cruise assist

The adaptive cruise assist (ACA) assists the driver with longitudinal and lateral control over the entire speed range – substantially enhancing comfort on long journeys, in particular. It incorporates the functions of adaptive cruise control, traffic jam assist and active lane assist. Depending on the model, the ACA uses the radar sensor in the nose of the vehicle, the laser scanner, the front camera and the ultrasonic sensors to permanently monitor the vehicle’s surroundings.

Depending on the sensor set, the system detects lane markings, roadside structures, vehicles in adjacent lanes and vehicles driving ahead. The ACA uses this information to derive a virtual vehicle path and “guides” the vehicle within it. The system also includes helpful steering intervention so that the vehicle remains in the center of the lane. In some models based on the modular longitudinal platform, the system uses also the laser scanner: The ACA detects if the lane is too narrow to allow side-by-side driving and enables offset driving through narrow stretches.

The adaptive cruise assist maintains proper speed and following distance via targeted acceleration and braking. The car automatically adapts its speed to the traffic situation and the route, for example at curves and cross-ways. In stop-and-go traffic as well as traffic jam situations, the ACA can bring the car to a complete stop. Depending on the duration of the stop, the car can start automatically again.

Hold assist

Hold assist enables convenient drive-offs when the car is on the usual inclines and descents of street traffic, and it prevents the vehicle from rolling. The system automatically switches over to the electromechanical parking brake when the car is stopped for a longer period of time while hold assist is activated. This ensures that the car will remain stationary even without activation of the parking brake. In conjunction with S tronic, after a stop at a traffic light, for instance, the car drives off as soon as the driver presses the accelerator pedal. The system is activated by pushing a button.

Trailer maneuver assist

The trailer maneuver assist makes it easier to maneuver in reverse with a trailer. Depending on the operating concept the driver uses the rotary/push-button control or the MMI-display to variably adjust the angle at which the trailer should be backed up. The image from the rear view camera on the monitor shows lines that serve as a guide. Trailer maneuver assist turns the steering wheel and directs the trailer onto the selected course. It allows a driving speed of up to 10 km/h  (6.2 mph) . If the articulation angle is too large, the system emits a warning, and it brakes in case of an emergency. Depending on the version, either a sensor in the rotating tow bar of the trailer coupling, that senses the angle between towing vehicle and the trailer, or a rearward directed camera serves as the technical basis.

Audi active lane assist

Operating at speeds from 65 km/h  (40.4 mph) , Audi active lane assist helps the driver keep the vehicle in the driving lane. A camera detects lane lines and the track that the car is following between them. In this process, the camera can distinguish between yellow lines in construction zones and standard white markings. If the car approaches a line without the turn signal being activated, the system helps the driver to steer back into the lane by means of gentle but noticeable interventions in the electromechanical power steering. In the MMI system, the driver sets how early the control intervention should occur. In the case of an early steering intervention point, the system guides the driver towards the middle of the lane by gentle, centering steering interventions. With a late steering intervention point, Audi active lane assist does not intervene until shortly before the detected lane marking might be crossed; then it gives a corrective steering intervention in the proper direction. In addition, the driver may choose to be warned by a vibration of the steering wheel when crossing detected lane markings.

Audi pre sense 360˚

The Audi pre sense 360˚ detects collision hazards all around the car and initiates specific safety measures. It includes the following driver assistant systems:

• Audi pre sense front

• Audi pre sense rear

• Audi pre sense basic

• Audi pre sense side

Audi pre sense basic

Audi pre sense basic initiates preventive safety measures for occupants as soon as it recognizes a critical driving state. It utilizes information from various vehicle systems to determine this. For instance, it intervenes if the Electronic Stabilization Control (ESC) sensors detect skidding or hard braking. Then the system pretensions the seat belts of the driver and front passenger electrically to reduce their forward or lateral movements. The side windows and sliding sunroof are automatically closed. In addition, the hazard warning lights are activated to alert following traffic. 

Audi pre sense front / Audi pre sense city

Audi pre sense front and Audi pre sense city utilize the data of radar sensors and/or the front camera, depending on the car model, to compute the probability of a collision. Within the limitations of the system, it warns of collision threats and initiates braking at specific vehicle speeds. Vehicles are detected in the driving speed range of up to 250 km/h (155.3 mph) , pedestrians up to around 65 km/h (40.4 mph) or 85 km/h (52.8 mph) depending on the model, as well as cyclists, depending on the system.

If a collision is imminent, the system warns the driver with visual, acoustic and haptic warnings based on a multistage warning concept. If necessary, the system provides braking assistance to reduce vehicle speed or initiates a full brake application to avoid the collision under certain circumstances. Actions are also taken to protect occupants. The hazard warning lights are activated, the seat belts are reversibly pretensioned, the seat position is optimized, and the windows and optional panoramic glass sunroof are closed.

Audi pre sense rear

Audi pre sense rear uses radar sensors in the rear bumper to detect an impending rear-end collision, and it initiates preventive safety measures. These include pretensioning the front seat belts by electric power and closing the windows and sliding sunroof. In addition, the system activates the hazard warning lights to alert following traffic to the critical situation. In this process, the Rear-end collision alert signal (RECAS) is triggered, which flashes the hazard warning lights at a high frequency. Audi pre sense rear is active in background over the car’s entire driving speed range with the exception of trailer towing situations.

Audi pre sense side

Audi pre sense side reacts in the event of a collision from the side. Amongst ohthers it uses the radar sensors of the crossing assist to calculate the probability of an accident involving traffic approaching from the side. The system can detect the threat of side collisions at speeds of up to approx. 60 km/h (37.3 mph) and apply preventative measures to help protect occupants. These include: activating the hazard lights, tensioning the safety belts, optimizing the seating position, and closing windows as well as the optional panoramic glass roof.

In an impending lateral collision at more than 25 km/h (15.5 mph) , the suspension actuators of the optional Audi AI active suspension raise the body on the side exposed to the danger by up to 80 millimeters (3.1 in) within half a second. The other vehicle therefore hits the car in an even more impact-resistant zone. The side sills and floor structure accommodate a large portion of the impact forces. Deformation of the cabin and the loads acting on the occupants, above all to the chest and abdomen areas, are reduced by up to 50 percent compared with a lateral collision with no raising of the suspension.

Audi side assist

The Audi side assist lane-changing assistant helps the driver to change lanes at driving speeds of 15 km/h  (9.3 mph)  and faster. It uses two rear-mounted radar sensors with a scanning range of roughly 70 meters  (229.7 ft) . If the system detects a vehicle located in the blind spot or approaching quickly from the rear, a warning LED is lit in the housing of the relevant exterior mirror. If the driver activates the turn signal anyway, the LED flashes several times in rapid succession.

Exit warning

Exit warning improves safety in city traffic. If the car has come to a stop and other vehicles or bicyclists classified as critical are approaching from the rear, the system warns passengers not to open the doors. The system does this using LED lights in the door panels. In a situation assessed to be hazardous, the LEDs flicker and light red. The LEDs of Audi side assist are also lit in the relevant exterior side mirror. The exit warning remains active for approximately three minutes after the ignition is turned off.

This system is based on the radar sensors of Audi side assist, which monitor the zones behind the vehicle and to the sides at the rear. Depending on the model the exit warning is extended by an additional feature: If the system is active, opening of the electronic door locks is delayed roughly one second.

Collision avoidance assist

Collision avoidance assist helps the driver steer around an obstacle in a critical situation. The system uses data from the two radar sensors and the front camera for this purpose. In calculating a suitable evasive maneuver corridor, it takes into account the distance, width and offset of the vehicle driving ahead. Collision avoidance assist is available over a speed range from approx. 30 to 150 km/h (18.6 to 93.2 mph) , and it assumes that the driver is actively steering throughout the maneuver. The driver is informed of the intervention by an indicator in the instrument cluster.

First, a jolt is produced to warn the driver of the hazard. If the driver then actively avoids the obstacle, the assistant applies a slight steering torque that helps by correcting the driver’s steering input or helping to make a lane change. Models like the Audi A8 (2017) use a specific braking of individual wheels – with it the vehicle is made to follow the computed course.

Curb warning

The curb warning identifies curbs that pose a risk to the tires or wheels. Prerequisite: The car is moving forward or backward at up to 10 km/h (6.2 mph) . If the system detects a critical situation, it alerts the driver to this in the optical parking system display on the MMI monitor. To scan the surroundings the system uses primarily the 360 degree cameras.

Multicollision brake assist

Multicollision brake assist automatically brakes the vehicle in the event of an accident, reducing the danger of skidding as well as the risk of further collisions. The function uses the relevant sensors to detect a collision; the severity of the crash and the speed reduction are calculated by the safety computer. If defined thresholds are exceeded, the safety computer sends a corresponding message to the Electronic Stabilization Control (ESC) control unit to trigger an automatic brake application, taking the system status into account. If the driver accelerates, the vehicle is not automatically braked. The same is true if the ESC, the brake system or the electrical system are not functioning.

Parking system, rear

Parking system plus informs the driver, visually and audibly, about obstacles in front of and behind the vehicle. The warnings are made when the distance to a detected object in the path of driving is less than 90 cm (35.4 in) – depending on the specific model – after the driver has engaged reverse gear and activated the system by pushing a button on the center console.

Ultrasonic sensors measure the distance, the MMI display depicts it visually. A white segment shows a detected object outside of the driving path. Red segments represent detected objects within the driving path. The virtual driving path display also shows lateral guide lines which are precalculated based on the currently selected steering input. Increasing frequency of the audible warning indicates that the distance to the obstacle is decreasing.

Parking system plus

Parking system plus informs the driver, visually and audibly, about obstacles in front of and behind the vehicle. The warnings are made when the distance to a detected object in the path of driving is less than 90 cm (35.4 in) – depending on the specific model – after the driver has engaged reverse gear and activated the system by pushing a button on the center console. Ultrasonic sensors inconspicuously integrated into the bumpers measure the distance. The MMI display depicts it visually. A white segment shows a detected object outside of the driving path. Red segments represent detected objects within the driving path. The virtual driving path display also shows lateral guide lines which are precalculated based on the currently selected steering input and thereby assists in convenient parking and exiting. Increasing frequency of the audible warning indicates that the distance to the obstacle is decreasing. At around 30 cm (11.8 in) distance to the detected object, the driver hears a constant tone – the signal to stop.

High-beam assist

High-beam assist utilizes a camera mounted on the interior mirror. It detects light sources – the headlights of oncoming vehicles, tail lights of other road users and the reflections of municipality limit signs, for instance – and automatically switches between high beam and low beam lighting. This provides for better visibility and a more relaxed driving experience. Drivers of oncoming vehicles are not blinded by glare. 

Speed limiter

The configurable speed limiter limits driving speed to a value set by the driver within the speed range of 30 to 250 km/h  (18.6 to 155.3 mph)  – which is very helpful within city limits or construction zones, for example. When the preset limit is reached, the vehicle gently throttles the speed down. The speed limit is not exceeded even if the driver applies more pressure to the accelerator pedal. However, the driver can temporarily override the limit by kick-down, and the speed limiter can be completely deactivated at any time from the steering column stalk. The speed that has been preset is shown in the instrument cluster.

Cruise control

Cruise control maintains a desired driving speed constantly starting at around 30 km/h  (18.6 mph)  (model dependent), provided that it can be maintained by engine power and engine braking effects. The system offers relief to drivers in this way – especially on long trips. At the same time, the constant speed mode of driving contributes towards lower fuel consumption and lower CO 2  emissions. The system is operated via a separate steering column stalk, and the preset driving speed is shown in the instrument cluster. The system is deactivated when the driver brakes. 

Crossing assist

Crossing assist recognizes critical cross traffic in front of the car and warns the driver of it both visually and audibly. At speeds up to 10 km/h (6.2 mph) , it initiates a short braking action when needed. Crossing assist is active at vehicle speeds up to 30 km/h (18.6 mph) . It uses data from the zFAS central computer, with the most important information here supplied by the mid-range radars and the laser scanner. If the driver wants to ease into an intersection or exit with poor visibility, he or she can push the parking button. This sends the images from the 360 degree cameras to the MMI monitor. They drastically expand the field of view, and the driver can choose from among multiple views.

Laser scanner

Together with the long-range radar and the front camera, the laser scanner forms a trio of sensors with various strengths that complement each other. It is these sensors and the central driver assistance controller (zFAS), which generates an image of the surroundings from all the sensor data, that make automated driving possible in the first place.

The laser scanner covers a field approximately 80 meters (262.5 ft) long, with an opening angle of 145 degrees. The roughly fist-sized component is mounted in the front bumper and, regardless of speed, emits moderated pulses of light on multiple vertical levels, which a mirror scatters in the shape of a fan. Having a wave length in the near-infrared range, the extremely short flashes of light are invisible and harmless to the human eye. They are reflected by objects in front of the car and return to the laser scanner in less than one microsecond, where photo diodes detect them.

The result is a detailed, deeply contoured, static image of the surroundings. The laser scanner displays other vehicles as measured cuboids, and it also measures such information as distance and orientation, which it distributes to the partner control units. With its large horizontal aperture, it detects cars entering the lane very early. Detailed information about structures on the side of the road, such as guardrails, round out the spectrum. Like radar, the laser scanner also works in the dark. Automatic cleaning and heating of the covering panel keep it operational even in inclement weather and spray as long as the conditions aren’t too extreme.

Maneuvering assist

Maneuvering assist recognizes moving and stationary objects larger than 10 centimeters (3.9 in) , such as a pillar in a parking garage or a moving vehicle. It helps to avoid impending collisions using warning steering impulses and by autonomously braking the car to a stop, provided that the car is traveling forward or in reverse at no more than 10 km/h (6.2 mph) . The system uses the optical parking system in the MMI to display its steering and parking interventions. The surroundings are scanned using at least the ultrasonic sensors and the 360 degree cameras.

Night vision assist

The night vision assist that Audi offers for multiple full-size models uses a far infrared camera. It reacts to the heat given off by objects. Converted to black and white images, the information can be viewed in the instrument cluster or Audi virtual cockpit. The cooler surroundings appear dark, while animals and people appear strikingly bright.

The system, which has a range of up to 300 meters (984.3 ft) , can detect people and larger wild animals at distances between roughly 10 and 90 meters ( 32.8 and 295.3 ft ) and highlights them with yellow markings. If a hazardous situation is detected, a warning sound is emitted. A warning symbol appears in the instrument cluster as well as in the head-up display. Depending on the headlights persons outside of town limits are illuminated with three short flashes of light.

Emergency assist

Emergency assist detects, within system limits, when the driver is inactive. In such a case, the system assumes control of the vehicle and automatically brakes it to a standstill in its own lane. Emergency assist monitors the driver’s steering activity. If it detects that the driver is inactive, it prompts the driver repeatedly, via visual and audible warnings and by brake jolts, to actively take over control of the vehicle again. With the first strong brake jolt at a driving speed below 80 km/h (49.7 mph) , the hazard warning lights are also activated to warn the surrounding traffic. If the driver remains inactive, despite the warnings, Emergency assist brings the vehicle to a standstill within system limits. The parking brake is engaged. The driver can deactivate Emergency assist at any time by moving the steering wheel, pressing the brake or accelerator pedal or by shutting off active lane assist or adaptive cruise control. 

Park assist

Park assist can automatically steer the car into parallel or perpendicular parking spaces. It uses ultrasonic sensors located in the front and rear bumpers and on the sides. The driver only has to accelerate, brake and shift gears.

The sensors measure parking spaces along the road while driving past them at moderate speed – a maximum of 20 km/h (12.4 mph) for perpendicular parking spaces and a maximum of 30 km/h (18.6 mph) for parallel spaces. A message appears on the MMI display when the system finds a suitable spot. The only actions required of the driver while parking are accelerating, shifting gears and braking. The system handles the steering. In addition, audible signals help the driver. Park assist will make multiple maneuvers, forwards and backwards, if necessary. It can also exit from parallel parking spaces. Depending on the model, the driver activates the system via either a button on the center console or a button in the lower infotainment display. The maximum speed for all maneuvers is 7 km/h (4.3 mph).

(Predictive) efficiency assist

Efficiency assist helps the driver to drive preemptively and save fuel. The system works closely together with adaptive cruise control (ACC) or adaptive cruise assist (ACA). It accesses predictive route data from navigation and Car-to-X information. In order to detect traffic signs and other vehicles, the efficiency assist uses the front camera as well as data from the front and rear-facing radar sensors.

The driver is shown corresponding information in the instrument cluster or in the Audi virtual cockpit and the head-up display as soon as it would be sensible to take the foot off the right-hand pedal. Symbols for speed limits, bends, roundabouts, towns, or downhill slopes that indicate to the driver to slow down are displayed on the basis of the route data and recognition of traffic signs. Depending on the model the gas pedal also pulses against the sole of the driver’s foot – a clear indication to take their foot off the gas.

If the cruise assist is switched on or the ACC is activated, efficiency assist regulates actively. It decelerates and accelerates predictively and adapts the speed to the course of the road and the traffic situation, also taking vehicles driving in front into account. If the driver so wishes, the system controls the freewheeling and coasting operation of the engine in cooperation with other control units. The predictive system always maintains a driving style that reflects the driving program selected – from efficient to sporty – and uses scope for recuperation in the Audi e-tron .

The driver can override the system at any time by accelerating and braking. In addition, drivers can individually activate, deactivate and configure many of their detailed functions in the MMI. Depending on the model, the control, for example, can be adapted to the course of the road in three stages: slow, medium or fast.

Cross traffic assist rear

Cross traffic assist rear warns the driver of approaching vehicles it deems critical when slowly backing up, such as when pulling out of a perpendicular parking spot. It uses the rear radar sensors for this. They cover the zone at the rear, including the driving lanes to the left and right behind the vehicle. The warnings are progressive – initially a visual warning is shown in the MMI display (in the park assist display). The situation is represented in a virtual top view and in the “rear” and “rear side” camera views. Red arrows behind the vehicle point in the direction from which there is a potential hazard. If the driver does not react to the visual display, an audible signal sounds before the system warns the driver with a brake jolt. This helps to avoid accidents while exiting parking spaces.

(Remote) parking pilot and remote garage pilot

The (remote) parking pilot and the remote garage pilot make parking extremely easy and convenient. Both systems enable the car to roll automatically into parallel or perpendicular parking sports or into a garage. They control the steering, the gas, the brakes and the automatic transmission. The driver either sits in the car (parking pilot) or monitors the maneuver from outside via smartphone (remote parking pilot and remote garage pilot). 

He or she activates the respective systems using the parking button on the MMI display. If the vehicle is moving at a moderate speed the ultrasonic sensors measure the parking spaces along the road. The garage pilot also uses the laser scanner. A message appears on the MMI display when the system finds a suitable spot. The driver can now stop, select smartphone control in the MMI, get out and start the parking maneuver from his or her phone. This is done by pressing the Audi AI button in the myAudi app and holding it during the entire parking procedure. The driver sees a live image from the 360 degree cameras on the smartphone display. The maximum distance from the car is six meters (19.7 ft) . The car pulls into the parking space at a speed of up to 6 km/h (3.7 mph) , maneuvering multiple times if necessary. The car can only pull forward into a garage. Once the vehicle reaches its final position, the tiptronic is set to P and both the engine and the ignition are turned off. When it's time to leave again, the driver can start the car using the smartphone and have it pull out of the parking spot or the garage.

The driver can also start the parking pilot while still sitting behind the wheel by pushing the AI button on the center tunnel console. This button must also be pressed throughout the entire parking procedure.

The (remote) parking pilot and the remote garage pilot function intelligently and conveniently. For instance, the sedan can also pull into a garage if it needs to drive in an arc to do so. Inside the garage, the car can pull very close to walls and obstructions such as bikes – or it will simply not enter the garage if there is not enough space. Its innovative laser scanner is particularly helpful here.

Reversing camera

The reversing camera simplifies maneuvering by showing the zone behind the vehicle on the MMI display. It shows the calculated driving track based on the steering angle as well as auxiliary lines and guide lines. For parallel parking, the latter lines precisely direct steering into the parking space in conjunction with steering reversal points. The blue pictured surface in the camera image indicates where the vehicle will be positioned after the parking procedure. The reversing camera is inconspicuously integrated into the handle trim strip of the luggage compartment lid. It is activated as soon as the driver engages reverse gear or pushes the respective button. 

Traffic jam assist

Traffic jam assist is a subsystem of adaptive cruise control (ACC) or adaptive cruise assist (ACA). In vehicles with an automatic transmission, traffic jam assist can assume certain steering tasks over a speed range up to 65 km/h  (40.4 mph)  on roads that are in good condition, as long as the traffic is moving slowly. The system uses the radar sensors and the front camera. It guides the car by making gentle steering movements within system limits and orients itself to lane markings, roadside structures and other vehicles on the road. When traffic jam assist reaches its system limits – such as when the traffic thins out or there is a sharp curve ahead – the driver must assume driving tasks again. If the driver does not, the system warns the driver in several stages. As a final measure, it autonomously brings the car to a safe stop.

360 degree cameras

The four 360 degree cameras on the vehicle scan the immediate vicinity and display obstacles within. Drivers can choose from different views that simplify parking and maneuvering. A virtual overhead view shown in the MMI display gives the driver an overview of the overall parking situation. The panoramic view to the front and rear covers an angle of nearly 180 degrees and provides better visibility when exiting tight parking spaces, courtyard entrances and confusing intersections. Guide lines in the reversing camera view make it easier to park in perpendicular spaces and to hitch trailers. The view from the front camera helps when maneuvering, as it detects obstacles in front of the car. The system is automatically activated when driving in reverse or by pushing a button.

An additional feature for some models is a virtual 3D view. The driver can use the touchscreen to steplessly swivel and zoom the image of the car and the actual vehicle surroundings. There is also a view of the front or rear tires so that the driver can pull the car up right next to the curb.

Traffic sign recognition

Camera-based traffic sign recognition detects traffic signs such as speed limit signs (including digital signs), no passing zones, entry restriction signs and other auxiliary signs, and it shows them to the driver in graphic form. They then appear in the driver information system and/or the Audi virtual cockpit as well as in the head-up display. The camera on the windshield also detects temporary speed restrictions such as in construction zones, as well as time- and weather-conditional restrictions. The system shows the currently applicable speed limit. For example, if a lower speed applies when the road is wet, this value is displayed – if the windshield wipers are on. Speed limits that are only in force at certain times of day are only shown at those times. In addition, the driver can choose a warning threshold as an offset to the legal speed limit. When this threshold is exceeded, a visual warning is given.

Central driver assistance controller

Conditional automated driving at level 3 is based on two innovations: a sensor set with the laser scanner and a central driver assistance controller known as zFAS, for short. The roughly tablet-sized computer constantly processes sensor signals and uses them to create a complete image of the car’s surroundings. To do this, it uses processors from leading global companies – NVIDIA (Tegra K1), ALTERA (Cyclon V), Infineon (Aurix) and Mobileye with the EyeQ3 image processing engine.

The sensor data is read into the “fusion” layer in the zFAS unit and is merged to generate a sophisticated model of the surroundings. It includes moving objects, stationary obstacles and a road model. The latter is generated from the conventional navigation map and from road markings and borders that the sensors detect. The vehicle is guided precisely within its lane in the model, and this positional information flows into the navigation map that the driver sees. This information offers the driver many benefits, such as in complex intersection situations.

The zFAS serves as the central interface for piloted driving functions and for nearly all of the assistance systems. Whether the given system is the crossing assist, the emergency braking function, adaptive driving assistant or traffic jam pilot – its functions are no longer coupled to just a specific sensor. Each system makes use of the vehicle surroundings model and can operate more effectively as a result of this model’s high precision. This makes it possible for the vehicle, for example, to recognize the tail end of a traffic jam and brake appropriately.

The principle of a central fusion level based on standardized sensor interfaces gives Audi another advantage – independence from the specificity of sensors. Developers can replace individual sensors whenever better devices are market-ready.

Dear Audi owners,

Please can you help me find a company that will retrofit adaptive cruise control to my 2018 A4 Allroad (B9)?

I love my Allroad, but I somehow messed up my factory order and didn't specify adaptive cruise control (ACC) which is part of the Driver Assistance Tour Pack, and it's annoyed me ever since

I've tried several companies including Richter (richtersport.co.uk) who said they couldn't do it, and Kufatec, who will do it, but they're based in Germany!

Does anyone one know a UK-based company that will retrofit adaptive cruise control?

Any help which would be very much appreciated!

My advice would be to look for Audi retro fit companies on Google. Light retro fit for example. Not that ive ever used them. 

Might be worth dropping these guys an e-mail .. they have a very good reputation and if they don't do it probably know if it can be done and by whom ..

Thank you Steve and Entwood. I will follow up on your suggestions... much appreciated! 

You're welcome 😊

I have just had Autologics fit a reversing camera to my A6 Avant. Really great job, did it at home on the driveway Give them a call.

These guys  have an offering for the RS4, RS5 and might be able to help.

Ben, these guys can do it, but you may not like the price!  I was quoted £5500 for an A6 Allroad.

Thanks 56Doc, I've been able to find a couple of places who will do it (see satnavsystems.com and hazzydayz.com) but yes, the quotes are up around £5,500! Thanks again!

2021 Audi SQ7 Review

See Edmunds pricing data

Has Your Car's Value Changed?

Used car values are constantly changing. Edmunds lets you track your vehicle's value over time so you can decide when to sell or trade in.

• 500-hp V8 moves the SQ7 with authority
• Feels nimble around turns for such a big SUV
• Premium cabin design
• Cramped third-row seats
• Infotainment system can be distracting to use

What's new

• A heated steering wheel is now standard
• Executive package now includes more leather surfaces
• Part of the second Q7 generation introduced for 2017

The 2021 Audi SQ7 is a three-row luxury performance SUV. The Q7 was already one of our favorite luxury SUVs, and that capital S front of its name means it gets a whole host of performance upgrades. Most notable of the superhero upgrades is a 4.0-liter 500-horsepower turbocharged V8. Some design tweaks also help it stand out in a crowd.

Cost to Drive Cost to drive estimates for the 2021 Audi SQ7 Premium Plus 4dr SUV AWD (4.0L 8cyl Turbo gas/electric hybrid 8A) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $4.17 per gallon for premium unleaded in North Dakota.

There are more and more performance variants of SUVs hitting the market each year, so the SQ7 has plenty of potential rivals. You might look at mainly two-row SUVs such as the BMW X5, Mercedes-Benz GLE and Porsche Cayenne, or you might go bigger with the BMW X7 or Mercedes GLS. Among them, the SQ7's mix of three rows of standard seating, 500 hp and relatively reasonable pricing is pretty appealing. Check out our Expert Rating to learn more and get our in-depth take on the 2021 SQ7.

A8 ADAPTIVE CRUISE CONTROL Retrofit

• Add to quote

Well done. Calibration is a must. It will take about 4 hours as the 4 wheel alignment has to be set before the ADC can be adjusted.  

Very very good!! What is the cost for all ? You are the best!!! bye,  

Thats an excellent retro-fit. Only wish it was possible for the B7 A4!  

Thanks guys, I'm writing the Part 2 of this thread with more interesting details and pictures because the quantity per post is limited. @a8 tech A calibration is planned but I have to find an AUDI Service more equiped than mine because he hasn't the VAS instrument for back up camera calibration so I don't think he could be equiped for ACC-calibration @Issac Hunt It should certainly possible in new A4 A5 but as we know the cooperation with Dealer is not limited to the C.P. removing there..  

I take my hat of to you. In my job as audi master tech i long for projects like this but we are governed by audi. This means if the retro fit hasnt been approved then we are adised not to alter the vehicles. I find this site fantastic and this retrofit shows me the technical know how is there and the skill level. having worked on a8s for some time i know how complex the electrical networks and soft codings are. Keep it up and if you live in the uk i think i would have liked to help you out. Very best reards A8  

Thanks again a8 tech  

Actually, I'd like to tell you guys an additional THANK YOU! Because you are the most valuable guys of this forum, all of you who are making any retrofits and shares the knowledge and the information. This site/forum is becoming a treasure! ;-) Thanks again!  

Fantastic upgrade, I have all the parts except for the cluster.  

Incredible a4ss4abt. You are the BOSS. Jaumet

Congratulations and Good job!! I shared some discussions with Darek70 : he is really a good guy. Gasy  

Adaptive Cruise Retrofit Part.2 In MMI menu CAR Adaptive Cruise becomes the first System you can Select and the functions are: 4 LEVELS for the Volume of Gong 4 DISTANCE presets. Cost of Parts CLUSTER+RADAR+SWITCH (used parts+various arrangements) EURO 1100 GATEWAY + FRONT-GRILL (new from AUDI) EURO 550 If you want to buy all the parts new from AUDI you have to calculate an amount of +/-3600 Euro !! It was essential for me to have only one supplier for the used parts and very important too it was the fact that Darek is a good and honest guy. This because the first Radar-Sensor he shipped me was defective and Darek provided to replace it with another working one. Here a layout of ACC conponents and some more pictures about MMI,mounting operations,cluster :  

Hello a4ss4abt. In my Q7 ACC, the SET UP of ACC its this. I Think, its possible, you can need to activate this, whith the Vag-Com. Jaumet  

You can watch the videos of ACC, here. Excusme for video cuality. AUDI Q7 ACC Carretera y Autopista con Peaje (Adaptative Cruise Control) AUDI Q7 ACC Autopista continuacion (Adaptative Cruise Control) AUDI Q7 ACC por las rondas de Barcelona (Adaptative Cruise Control) Jaumet  

Great job! Would it be possible to post a pic of the Cruise/ACC 4E0 953 521 A

a4ss4abt said: I have checked in Adaptation CH.13 there are only 3 channels, 1/2 are dedicated to the Gong adaptation and the third is the Heating sensor not used anymore. If you can send me your 13 ADAPT.CHAN.MAP I can easily compare mine but as the Q7 Radar-sensor 4L0 910 561 it's not the same for A8 it can be also possible it has some different functions.

Very impressive and well done a4ss4abt!

Super mod! What an incredible job!! This was an option I wanted to ask you for.......so, Thnx!!  

a4ss4abt, you really did an excellent job!  

tecman said: I wonder if it can be done on car with manual gearbox? I've quickly checked online audi configurator and it let me choose it, but I can't see it working with manual?! Can you? manual gearbox. Ps. I sent you PM few days ago, did you get a chance to read it? Click to expand...
