    2013 Touareg 7P US model retrofitted with Euro tow bar & controller

    Hi all,

    When I moved from Texas to the Netherlands I had the good fortune to bring the TREG over. Most functions carry over except for the rear fog light which took some finagling but works fine now. Also swapped out the US receiver hitch style tow bar and control module (7P0-907-383-F) for the electric swiveling euro style tow bar and control module (7P0-907-383-C) that I obtained via a local salvage yard.
    After the install (with the tow hook swiveled "in"), I managed to actuate the swiveling mechanism just once and now it is in the "out" position.
    This is what I know so far:
    - All trailer lights / functions work when connecting to the 13 pin euro style connector, at least with regular style bulbs. Not sure with LED's.
    - The swiveling button in the boot lights up as intended when opening the hatch
    - When pressing the swiveling button, the tow hook does not move
    - Coding for the Euro style control unit 7P0-907-383-C that it came with is 0106040000000000 which seems to be correct according to many VCDS scans that I was able to verify against.
    - This coding throws the following error however on my unit:

    02588 - Swiveling Trailer Hitch
    005 - No or Incorrect Basic Setting / Adaptation - MIL ON
    Freeze Frame:
    Fault Status: 11100101
    Fault Priority: 2
    Fault Frequency: 1
    Reset counter: 221
    Time Indication: 0

    - When I change the coding to 0106000000000000, this error goes away, but the swiveling button in the boot does NOT light up as intended when opening the hatch and the no response when pressing the button either (tow hook does not move).

    I am sure that in order for everything to operate as intended, the original coding needs to be reinstated. Just curious for clues as to where to start my fault finding mission.

    Attaching full scan for completeness' sake:

    Haven“t "played" with such a towbar; but to me, it looks like some missing calibration. Are there any options to carry out a calibration?

    Try and download these 2 files:
    7P-69.lbl
    4H0-907-383-V1.clb
    and copy them to:
    C:\Ross-Tech\VCDS\Labels\User

    Then check in [69] controller, if it is possible to do [Output Test-03] and select the only "Selective Output Tests" that is available
    "Swivel Motor: Initialisation"

    Label file says .lbl, but file itself is .clb. Is this a typo?

    Yes it is, I have changed the 7P-69.lbl now.
    But it should load correct anyway, if I recall right.

    Thanks for the suggestion.

    Only got to it just today and label file that is confirmed to be used is USER\4H0-907-383-V1.clb but "Selective Output Tests" remains greyed out..

    Looking forward your continued and valued support.

    Thanks, I just found a bug in VCDS, or it is a "feature" unknown to me
    Try and download the same file again, same name it is updated know and then test again.
    Now there should be 2 "Selective Output Tests"

    Hi NEtech, Thanks much for your help. I feel we are making progress, but not there yet entirely;
    - "Swivel Motor: Initialisation" errors out "This output is not supported by control module" with Error code 7F 22 31
    - "Dont think this can be used!" actually unlocks the swiveling tow hook (in both in or out position, so kind of useful at this stage where I can now manually swing the hook in or out (the wife and her shins are thankful!).

    Curious what else we can try. :-)

    RGds, JP

    Maybe try:
    "Dont think this can be used!"
    Then:
    "Swivel Motor: Initialisation"
    Then move swiveling tow hook, manually out and then back.

    Hi NEtech,

    Followed your suggestion and am noting that upon unlocking (with "Dont think this can be used!") the LED in the trunk space button for the towhook is blinking; at least it knows that the unit is unlocked and shows the correct warning.

    Activating "Swivel Motor: Initialisation" immediately errors out as before with code 7F 22 31. Manually swiveling in and out does not do anything except that the towhook locks into place on full in and full out (requiring unlocking each time).

    A full scan does not reveal any errors in 69 - Trailer:

    No fault code found.


    Supp. Codes - 18 on 69 - Trailer reveals the following active fault code though: DTC 02025 / failure mode 007.

    I think this points towards a potential wiring problem to the swivel motor. Time to remove bumper cover (again!) and go on a fault finding mission..
