Concerns:
Wire harness for rear lid
Cause:

according to specifications on the affected vehicles due to a manufacturing error.
If this is the case, it can lead to a malfunction of the heated rear window as well as signal disturbances to
radio reception.
Action:
Check wire harness for rear lid and rework if necessary.
