This TSB applies to a number of VW models, including 2007-2008 Eos, 2006-2009 Rabbit, GTI and R32, 2006-2009 Jetta, 2009 Jetta SportWagon and 2009 Tiguan.
The steering angle sensor cannot be adapted after the steering wheel electronics module J527 has been replaced.
The J527 was packaged incorrectly, even though the packaging matches the number stamped on the module. The part number in question is 1K0 953 549 BK.
To verify that the correct part has been received, the part number that is stamped on the case must be compared to the part number recovered with the scan tool.
If a fault log has been printed since the part was installed, compare the part number under “Steering Column Electronics” to the component part number.
If a fault log has not been printed since J527 replacement, perform the following:
- Select “Vehicle Self Diagnosis.”
- Select “On Board Diagnostics (OBD).”
- Select “16 – Steering Wheel Electronics.”
- Review the part number in the upper right hand of the screen to verify that the index is NOT “AM.” If “AM” is shown, replace the J527.
