Hi,

I had Westfalia detachable aftermarket towbar installed in a garage (not official Audi), but they failed to code all the modules in my car.
All other modules seem to be fine except the "13 - Auto Dist. Reg (J428)" module for which there are no label files in VCDS, thus it was not modified. The garage also uses VCDS.
My car is Audi A4 Avant 2.0 TDI Multitronic 2013 (built 05/2012). The car has start/stop, front/rear parking aid (no cam), lane maintenance, auto trans, front wheel drive, adaptive cruise control.

The module (8K0 907 561 B) is now reporting fault (Control Module Incorrectly Coded) and adaptive cruise control (ACC) and lane maintenance functions do not work at all.

I saw a recent thread on the same issue in this forum but it was for the older control module of Audi B8 2009 (Byte1: set bits 0 and 3, clear bit 4).
I have a newer "B" version of the module so setting these bits 0 & 3 do not work for me (value out of range error). Bit 4 already cleared by default in my module.

Any information would be appreciated to help determining the correct coding for the adaptive cruise control module, before giving up and taking the car to Audi service (which has long waiting queue at the moment) :(

The following coding has already been done:

Code:
01 Engine
03 ABS Brakes
09 Cent. Elect.
13 Auto Dist. Reg - *** INFO MISSING FOR CODING *** (SOLVED)
19 CAN Gateway  - added module 69 Trailer
46 Central Conv.  - I found a trailer setting here also and set it although not sure if needed, Byte12: bit5
5C Lane Maintenance - *** INFO MISSING FOR CODING *** (SOLVED)
69 Trailer

It was my thread you were referring to. :)

I see you have ACC3 and mine looks to be ACC2. I tried Westfalia tech support (to no avail) and a local trailer centre tried his guy at Westfalia and couldn't help either. However, they both kept on saying set Byte 0, Bit 0. You've seen from mine that it wasn't as simple as that, however, you may as well try it.

As we say here in Newcastle - you've got nowt to lose! :D

*edit* I see you have automatic transmission. Please check in there whether you need to code that module too.

Yes it was your thread. Thanks for opening the topic :)

Unfortunately setting Byte0 Bit0 does not work either. I get the same "Error 31: request out of range" message, the same as for Byte2 bits 0 & 3 earlier.
I guess this error means only that the coding value is not valid, not like I would need to do some secure log in etc first.

About the "02 Auto Trans": VCDS does not show any explanations for the bits, so I do not have any clue if anything would need to be changed here. I have not seen any trans. coding in other threads related to tow bar installation though.
The same goes for "5C Lane Maintain." module.

I didn't require a Login or Security Access code to enable re-coding; yes, Error 31 is simply that the code you have offered is rejected by the controller. I had numerous Error 31s until I was provided with the correct one.

Give it a week or so, NETech may be able to help you too.

Thanks. I have no other choice than wait at the moment :)

Have you changed the Coding in 13 Auto Dist. Reg, compared original ?
It looks a little special, could you please send VIN.

I edited the first original post and made complete VIN visible in the scan result. Please take a look.

13 Auto Dist Req coding has not been changed. Luckily I had a scan done (for some modules only) before the tow bar installation, so I could verify that this module was not re-coded.

The car was originally registered and taken into use in Germany (just imported to Finland).

You know the car is not prepared for Trailer (engine cooling/ your/owner responsibility) !!

I would use 00F6B9 for [13]
There is also 0122001 for [5C]
Remember to change non-zero values in wsc, importer, device no., like explained here before accept coding.

Hi,

Yes, I am aware of that the car has no preparation for trailer. I don't think this is a problem for me, but good to know.

The new code for 13 Auto Dist Reg WORKS! Adaptive cruise control is now back and alive. Big thanks. I wish you had the label file with bit explanations available for this in VCDS ;)

The new code for 15 Lane Maintenance WORKS! Lane maintenance functions is back and alive. I must confess now that the lane assist was turned off by the garage using the button in the turn signal lever, and I have missed there even exist such button (new car). So the coding was never a problem for lane assist not to work. I feel ashamed now :o.
It works also without the new coding provided, but I will use the one as also based on my own investigation the provided code is correct when trailer is installed. Just wanted to add this info here if someone else ever faces the same :)

I come bakc later and summarize all the codings done for my car for tow hitch installation. Might be useful others.

BIG THANKS FOR THE SUPPORT!

Wow - cannot thank you enough for this coding above. I too had no active cruise control on my B8.5 A4 following on from my Westfalia towbar home install and this sorted out the last piece of the puzzle! I found the threads on other Audi forums showing me where to do all the long coding changes for the towbar but those steps are missing this piece. Everything now works perfectly and I am super pleased! Thanks a million! Charles
