VW Touareg (7P) Steering Wheel Electronics

From Ross-Tech Wiki


Coding for this Control Module is normally done via Software Version Management (SVM).
If the old Control Module is still accessible read/copy it's Coding to the new Module.
If a complete Auto-Scan containing the original Coding of the Control Module is not available Coding information is available while connected to the vehicle with VCDS using the Long Coding Helper. If you are unable to build the coding using the Long Coding Helper Registered Customers can emailthe complete Auto-Scan and vehicle repair history.

Basic Setting

Steering Angle Sensor (G85) Calibration

[16 - Steering Wheel]

Turn steering wheel at least 30 ° left or right and back straight ahead (Tolerance: ±0.5 °).

[Security Access - 16]
Enter 40168
[Do It!]

[Basic Settings - 04]
Group 001
Activate the Basic Setting.
After a successful basic setting, field 3 should say "OK".
[Done, Go Back]

[Meas. Blocks - 08]
Group 033 Field 3 (Steering Angle Sensor -G85-)
Specification: 0.0 °
Tolerance (when straight): ±0.5 °
[Done, Go Back]


  • To confirm the status of the G85 calibration see MVB group 032.
  • If the basic setting group results in an error message verify the live G85 reading is ±1.5 °. Readings such as 359° would indicate the slip ring is mechanically out one full turn.
  • The slip ring is the 16-Steering Wheel Electronics module. If the vehicle deployed Airbag(s) and the slip ring was replaced make sure the module is long coded using VCDS.
