Hello folks,
another issue from our VW :) --> Touareg V6 Tdi 7L
So the level lock button does not work
the level up down button does not work
the sport/auto/comfort button does not work.
So what we have done
1. Scan the system and the output error is 01176 control head for vehichle leveling p28 we sucpect this HEAD is the faulty one but we don`t know where is it and what can be done diagnose and repair adapt or replace it
2. Test and Adapt the module of Level Control everything seems to be ok the car is moving up down due to adaptation process no issue
3. Take a spare Level Control Module second hand for test, the new one seems to be 1200 Euro which is not acceptable -
3.1 we drove the car to one service cannot connect to this Lift module and might be faulty.... but we connect to it with success with ROSS-Tech VCDS and make adaptation with it diag and so on
3.2 We put the spare module and when scan it it has 8 errors from every sensor on the system of leveling include that HEAD error i don`t know is this normal or not
4. From the official near service sad that they cannot fix the issue
5. Abandon the VW at the parking to gather thoughts :D :)

Control head E281 communicates with the level control module J197 (34) over a single k-line. Check continuity of they wire from E281 pin 7 to the level control module pin 15. Also check the fuse for E281. With VCDS in 34 you can see the status of E281, which buttons are pressed etc.

Hello to update the topic!
We revealed the problem
Font Line Display device Electronic device Rectangle

what we have done
removed the fuse for it was 5A on right side panel (passenger side) check it with the Fluke multimeter it was ok
so we put it back on place
then we attached the vcds
log into the module cleaned errors and test MVBs while cruising the buttons for control of the level
everything was ok
adapt the s***T clear stored error no errors after adaptation
and now the VW lift up and down without any issues.
The adapatation of the module we performed on the following steps
1. login into the module
2. Enter security access 31564
3. CH01 measure the distance between center of the central hole cap to the edge ot the central side ot the fender Enter the measured distance in MM Test & Save.
4. CH02 measure the distance between center of the central hole cap to the edge ot the central side ot the fender Enter the measured distance in MM Test & Save.
5. CH03 measure the distance between center of the central hole cap to the edge ot the central side ot the fender Enter the measured distance in MM Test & Save.
6. CH04measure the distance between center of the central hole cap to the edge ot the central side ot the fender Enter the measured distance in MM Test & Save
7. CH05 Enter Value 1 Save
I Dont know how precise was this adaptation because we didn`t measure it like in a lab but will make it someday in better condition on perfect plain terrain with closed doors and out of the car if it has sense to do it in such manner how do you think ?
Greets and very thank for your support and time !
The beers are onsite ;)
