I've been trying to find the correct codeing for my ACC, but it's not possible.

Can anyone help me please?

Instrument is beeing replaced with the correct one within this or next week.

Thanks

I've coded 01, 16 and 19, but I'm missing something in 13 (and perhaps in other modules ;))

While looking through many Autoscan, I would say you need an 8K0 907 379 CN ABS.
How adaptation channels are in [03-ABS] I don't know, a secure access is needed.
Then coding in [13-Auto Dist.] could be: 00A4B1

Thank you very much! The coding was accepted :-)

However changing the ABS unit was not part of the plan :( I can see that " CN " ABS unit also supports TPMS and Hill Hold, so I'll get 3 functionalities when I'm changing it :)

Hello Diskoboy
I made same retrofit on Audi A6 2012, but there it is more complicated. System in A4 is more simple. You dont need to change door switch, instrument cluster is also ok for ACC (8T4) (but there is error from instrument cluster in radar, hope it is only due coding instrument cluster.) I saw also error in 5F (hope you retroffited it too)

Can be clean by Vag Can Pro in one click or by Vin Patcher:

http://uloz.to/xN4udNw8/vin-patcher-sw-zip

Use instructions

1. Select "Create SD" in menu option and select the free SD card.
2. Insert SD into MMI/RNS and run the script
3. Press "open" button and select the texts.jar file from root of SD
4. Type you VIN number to the VIN field
5. Press "Patch" button
6. Wait for Patch OK message
7. Press "Update SD" in menu
8. Turn on MMI and insert SD card, wait for script run

I am not sure if you really need to swap ABS... In Etka there is no difference between ABS assign to 8T4 PR code.
Try secure access in ABS - 61378

Thanks. The security Code is allready shown in VCDS.
What should I've change in 03-ABS ?

Hello Diskoboy
Are you sure, that you have wire to ABS from ACC ?
In long coding helper is not in VCDS more infos about coding ?
Try these coding for ABS: (after security access)
031544
160504
179D4C

Try ACC coding:
007DA8


I found somewhere some more infos but not in English:

Activation acc adaptive cruise control + (Audi braking guard)
Encodings possible to change 00EEF0, 00EEE9 00A0D0 0079C0 /// ??? Not sure for what module he mean.

ACC activation, enter the hidden menu, car> cardevicelist> ACC and AWV, cardmenuoperation> ACC and AWV put the value 5, restart MMI

Module 1 Engine: Byte 5 - 6 bits from 0 to 1 (if you have cruise control, remove the bit 5); This is long coding: 12194012234403080000, I have a 2.0 TDI engine from 120 hp;
Form 19 can-gateway: Installation List add to the module 13 (radar), then I left the encoding you had (000,303); my original was 00CF07;
16 steering module: Byte 2, in addition to bit 2 (cruise control) is also turned on bit 3 (ACC); 00001F is instead of 000017 (CCS);
17 instruments module: 4 bytes bit 2 to be activated;
56 radio module; 4 8-bit bytes to be activated (ACC), and byte 10 bit 6 to be activated (Audi braking guard);
13 Radar: I left the code that was (0079C0), (OK 00EEF0) though they had seen on the internet and tried to accept other codes. Maybe I'll try later to see what happens. I also added: Adaptation - channel 7 - 0 to 1 - save ... .so you can adjust the default value of the distance by which part of the ACC.

Thanks XPepino. I'll test the codings tomorrow and give some feedback :)

Looking in ElsaWin there should be no wire from ACC to ABS.

The only wires are:
T8a/1 - Ground
T8a/2 - Can Extended High
T8a/3 - Can Extended Low
T8a/8 - Fuse SC 9

Since the car was born without Cruise Control, it could be that I'm missing a wire from T94/45 (ECU) to T16f/5 (Steering Colum). I'll have to check that tomorrow as well.

No. He does need to change his ABS unit. His current one is 1AS. He needs one with pr code 1AT. 1AT is required on cars with ACC, hill hold, etc.

Quite correct; as the functionality mentioned (ACC, hill hold, braking guard etc.) all require an ABS module that can supply its own hydraulic pressure. The 1AS unit does not have the hardware to pressurise the hydraulic circuit.

Just bought a almost new ABS unit on eBay. Now lets see when it's arriving.

Thank you all.. This thread will continue when the ABS unit arrives. ;)

The one Netech suggested: 8K0 907 379 CN

Found whats looks to be a new one on eBay for 255€ (approx 290 USD) including shipping

The CN would most likely work, but it is incorrect for your vehicle's build date. I would have gone with the CH version. Just my .02

Well - now it's bought and shipped so let's see how it goes.

BTW - I've really like your signature :-)

Finally I think I have time to change the ABS unit this weekend.

Can I take the coding from the old unit to just copy/paste it or is special (online) coding needed ?

Does the ABS unit have component protection?

ABS unit shouldn't have CP. I would start a new thread with a new autoscan regarding the changing of your ABS unit. Never assume coding is the same when going from one unit to another. Online services shouldn't be needed but hopefully someone at RT can generate the new coding string for you based on your current one (if needed).

Hi,

I can see you replied on few threads about ACC, i hope i pick you brain re my issue. :)

I've got a 2016 A5 sportback (8T), 1.8tfsi Multitronic. From new, I have been experiencing a strange "tick" or "knock" sound from behind the dash, left side (above pedals, where various relays are or from behind firewall??). Every time i accelerate, i can here it at approx 15-17 km/h, kus one single "tick" or "knock". I mean not only the first time i accelerate after i start the engine (in which case breaking system does something to calibrate), but every single time.

The only time i do not hear it is when i breakdown using gears (not breaks) , after that no tick during acceleration. I even though that it was something to do with pads in the front. The dealer took pads off, used paste, etc. put it together and said everything was fine there.

Interestingly enough, when they were working on my car, i got a loaner Q5 and i could hear the same sound, not as pronounced though. Maybe because it was diesel and general noise from the engine was higher.

I've had A4 and Q5 (both FL, 2013-2015) before without ACC and never experienced such annoying sound before. I tend to think that this "tick" or "knock" sound is due to the ACC installed on the car. The Q5 loaner was also equipped with ACC. I am therefore questioning, what is the difference under the dash (or that direction, possibly straight behind the firewall?) between a car (A4/A5/Q5) with and without the ACC? Any additional relays use by ACC? Different ABS module or different logic of ABS operation? Anything different in the breaking system otherwise? In the ACC system, is there something special happening around 15-17 km/h (anything activating/deactivating or engaging/disengaging)?

I would appreciate any thoughts! :)
Thank you!
