Adaptive Cruise Control nachrüsten
Hallo,
ich hab den Tempomat eingebaut und könnt den " adaptive cruise control Sensor" günstig ranbekommen. Die Frage ist nur, in wie fern ich damit das System nachrüsten kann. Was fehlt noch. Wo würde ich preislich landen?
Ich habe kein Navi, also kein MMI.
... Danke

Moin, dann habe ich es endlich geschafft ACC für meinen Audi A4 8k 2008 2.0 TDI CAGA mit JJG Getriebe nachzurüsten :) War ein langer Kampf wegen anderer Getriebeübersetzung als der Audi A4 8k der ACC hat (ab 11.2008 glaube ich…). Unten gibt die Anleitung ohne Getriebeaustausch :) Aber auf Englisch weil Deutsch nicht meine Muttersprache ist und vielleicht haben auch andere Interesse daran…
As mentioned above, I wanted to retrofit ACC. After doing everything according to instructions in this thread etc. and flashing the ECU with new software, the gear indicator in the instrument panel disappeared and ACC was disabled in 5th and 6th gear (where you would really need it). After a lot of research, I found out that the gear ratio was changed before the version with ACC was released. KXP is the number of the new manual gearbox with longer ratio I believe… In some Italian forums, they have managed to retrofit this, but only after changing the gear box. I have finally managed to do it with only changing the ECU software :) It took A LOT of reverse engineering and trial and error editing the flash file.
My original configuration:
Audi A4 Avant 8k 2008 2.0 TDI CAGA 143PS and JJG manual gearbox – First time registered 01.06.2008.
ECU HW: 03L 906 022B SW: 03L906022B version 9970
(No responsibility taken if this does not work on your car, and if you really want to be 100% sure not to get IMMO problems or similar, you may consider to extract the ECU and backup the complete SW with internal flash and EEPROM in bootmode.) However I did it according to below without any issues… NB! Important to ensure stabile voltage during flashing! E.g. connected to power source or (not optimal) good status of battery….
Step by step guide:
After having done everything according to the standard ACC retrofit guides, do the following to adapt gear ratio.
1. Read out the Internal flash data of your ECU SW xxxB, 2048 kb. You can e.g. use Galletto FGtech v54 via OBD. Bootmode was not required for me.
Flash the ECU to a SW which supports ACC. SW xxxB does not support it. I used MJ version, and flashed with VAG CAN Professional. Flash files can be downloaded via e.g. erWin in the frf format.
New SW: 03L 906 022MJ version 9335
2. Read out the Internal flash data of your ECU SW xxxMJ, 2048 kb. You can e.g. use Galletto FGtech v54 via OBD. Bootmode was not required for me.
3. Using a hex editor (or even better tools such as WinOLS) update the area which contains the gear ratio for the instrument panel.
In my flash it was found at address:
a. 1A0ED2 to 1A0EE8 – Axis transmission ratio between engine speed and vehicle speed:
My old B SW (new values for your MJ file):

If you have the same values in your B and MJ read flash files all should be good! I have identified this using various flash files read for SW such as B (not ACC suppport), MJ (ACC support), JM (ACC support), and changing MJ vs B differences gradually.
c. 1F9054 to 1F9078 – Min, max and change of gear ratio between engine speed and vehicle speed:
If you investigate DAMOS files it seems to be second area which also represent gear ratio, however it is not required to get the gear indicator working in the instrument panel.

d. Save/export the bin-file.
5. Flash the file to the ECU using e.g. Galletto FGtech v54 via OBD. NB! The new checksum needs to be correctly updated using your editor (e.g. WinOls” or flashing software (e.g. Galletto).

Did you do all other codings which are necessary for ACC?
Yes, all codings have been done on modules 01, 13, 16, 17, 19. Recalibration of G85 done.
After changing the coding for module 13, there is a new error:
16352 - Control Module - Electrical Error
014 - Defective - Intermittent

right gateway?
with exetened can
Yes, can 8t0907468aa. If the can is the wrong version, module 13 is not accessible. CP removed for can and radar. Maybe there is a difference between fuse panels? Because my 12V wire goes to the brown panel on the passenger side and original wire goes to the trunk panel....
ACC works! It's great!
The problem was the 12V wire, it was plugged in the brown passenger fuse box where it had permanent 12V, but the original fuse box receives 12V only on ignition. So the module was remaining under 12V when ignition was off but the others did not have 12V anymore so this is why the errors apearred.
So I just had to move the wire from the brown fuse box to the black one next to it that receives 12V only on ignition.
One error still remains on module 13, but ACC works, maybe the error will clear out:
16352 - Control Module - Electrical Error

Regarding the sound warning, I have MMI 2G and have enabled via hidden menu the ACC option, so everything is available in CAR menu. I have selected the tone for the gong to medium, when I select it there is a sound, so the gong works. But when I reach 30km/h and acc deactivates, there is no gong! Any ideas why, maybe I have to select something else for the sound warnings? Same for braking guard, I have approached another slow moving vehicle and there was no sound warning.
Thanks
thats what i said !!!
Yes, you were right, thank you!
So any ideas for no sound warning? I have made this video, close to the end you will see that acc is slowing down and when it passes the 30km/h margin there is no sound, car is still in gear till close to 20km/h, so acc was not deactivated.
activated breaking guard in mmi menu ?
Yes, braking guard activated, warning activated.
In ACC menu volume for warning selected to medium, driving style selected to standard.
Hi guys. I did my ACC retro last week but still having problem with coding. I tried every coding from this thread and many other websites and one error still persist '01044 - Control Module Incorrectly Coded'. I live in Ireland and I suppose it could be rhd/lhd coding problem. I drive 09 A4 2.0tdi with manual gearbox. Do you have any idea where the problem is? Thanks!
which coding do you use now?
Trailer coupling: yes/no?

do you have a facelift radar?
index?`
I've tried many codings, no change. At the moment there is 0079C0 I think. And the radar number is 8K0 907 561 with no letter. No trailer hitch.
SW version?!
