    A4 B6 2002 - Cannot perform VIN Adaptation Steering Control Module - Cruise Control

    (moved from new user forum)

    Hello everyone,

    I recently tried to do a cruise control update on my A4 B6 tdi quattro 2002.
    Thanks to plenty of information on this site, and others, I felt reasonably well prepared.
    Figured I needed to upgrade my steering control module from revision F to N to support this, and duly obtained a used module 8E0 953 549 N.

    As soon as this is fitted, I get some errors flagged for ABS (as expected) and also the VIN mismatch from the steering controller...



    Proceeding to follow the VIN adaptation instructions for steering module 16 (select channel 81, enter 00111 as new value) I am now stumped, as the "new value" field is greyed out, and hitting "read" has no effect...



    Can anyone throw any light on this?

    I actually assumed it was a faulty 8E0 953 549 N module and decided to obtain a second module. In the meantime I replaced my N module with the original F and performed G85 steering calibration, ABS recoding, and ABS/ESR system test (all required to get the ABS back functioning, and achieved all that, though not without a little frustration!).

    Now I have refitted the second N module and am back in the same situation, unable to relearn the VIN as "New Value" cannot be entered.

    Doubly stumped. Any ideas?

    Here is the full autoscan of the car, should this be of interest...

    (There are a few "permanent faults" including the engine solenoid valve, the alarm battery is dead causing central convenience issues, and the AC faults 01810 - Actuating Motor for Temperature Flap; Right (V159)
    41-10 - Blocked or No Voltage - Intermittent
    00716 - Air recirculation Flap Positioning Motor (V113)
    41-00 - Blocked or No Voltage
    which are presumably associated with the annoying "hunting" noises that come from the flap motors in the AC when the car sits after stopping the engine, and if anyone know how to stop this I would be very happy! All in all the car runs well and does not throw up any other spurious faults, the AC never worked since I got it 4 years ago).

    That's puzzling. [Read] should produce a Stored Value and enable the New Value field.

    Yes, that IS indeed puzzling. I am a relatively new user to VCDS, but have used it to tweak a few simple things in the past, and I did manage to use it to recode the ABS unit and recalibrate the steering sensor when swapping back to the F version steering control module. But I simply cannot get the VIN adaptation to work (I did attempt to do the process highlighted in the first reply to this thread above). I have tried two different revision 8E0 953 549 N modules, so I dont think its a fault on the steering controller module.

    I wonder, are there any built in diagnostics I could enable or examine to see why VCDS is unable to perform this function on the module?

    Thanks,
    Tim

    Yes, let's try the following:

    [Options]
    Set Debug Level to 1024
    [Apply]

    Now without exiting VCDS, go straight to:
    [Select]
    [16-Steering Wheel]
    [Adaptation]
    Channel 81
    [Read]

    Give it 30 seconds there.

    Then back out of VCDS gracefully and look in the Debug sub-folder. There you should find a file named DEBUG-16.DLM. Please e-mail it to Support@Ross-Tech.com along with a link to this thread.

    Done. Look forward to the analysis

    Hello Tim,

    The team received and evaluated the files. They can see Adp channel 81 takes a while to get a response from the 16 module but the cause isn't entirely obvious.

    The plan at this point is to wire a handful of those B6 modules on a bench to see if this can't be duplicated in-house. We should have an update for you next week but feel free to bump this back up if you don't hear anything by Tuesday!

    Hello,

    Wonder if there is any further news on this problem, or any likelihood of a solution?

    As the car is rather mature (2002) could it be worth trying older software, though as I have a HEXV2 interface I guess there is a limit to how far back I can go.

    If there is realistically no likelihood of a solution I may see if Audi can perform the function with their own tools. I have a long 2000 mile trip coming up soon and I either ideally would like the Cruise working, or at least the ABS restored, which would mean swapping back to my original steering control module.

    If there is any way to perform further diagnostics on the problem then I would be keen to work with you to address it!

    Many thanks,
    Tim

    Well, I have an update for you...

    Visited an audi independent today who also had a HEXV2 interface and VCDS 18.9.x (didn't get to check the exact subversion).

    Using his laptop, windows 7, and HEXV2 interface the VIN adaptation of the steering control module worked straight away: The NEWVALUE field was able to accept an input value in the expected manner.

    I was previously attempting to run VCDS on Windows 10 pro on a fairly high end i7 laptop (Asus N580).

    This leads me to suspect one of the following...

    1. There can be an issue with the version of windows or laptop
    2. My HEXV2 interface is defective.
    3. There is a significant difference in recent subversions or firmware of the interface that could lead to the problem.

    I will attempt when I get a chance to install latest software on a windows 7 or 8 laptop and check to see whether the component VIN adaptation screen is available with my interface.

    If I still cannot get this function to work then I would probably like to get my HEXV2 interface replaced.

    My cruise control is now up and running properly anyway: The remaining steps, ABS reset and coding, G85 calibration, ABS/ESR system test went smoothly.

    Food for thought anyway.

    Thanks,
    Tim Knights

    I've not been able to get our 8E MFSW control module to talk on the bench here. It's a shame because I have the same part numbers as you for 0x17 and 0x16. 0x17 talks and sees 0x16 on Comfort CAN, but 0x16 doesn't respond to the scan tool :-(
