Service
This TSB may apply to vehicles still within the new model launch repair authorization period!
- For vehicles still in the launch phase, the workshop must create a case with the Technical Assistance
Center (TAC) per the repair authorization. Reference this TSB in the first line of the TAC case.
The aim of this service info is to help locate issues related to the loose wheel warning or tire pressure. The following
points may help when processing the complaint (although it is not always necessary to perform all steps):
+ Update the vehicle to the latest software version (perform campaigns or other TSBs).
+ Check addresses 812C and 0003, and 0065 (if available) for relevant DTCs.
+ If DTCs have been logged for individual wheels or all four wheels, performing wheel balancing or swapping
wheels over may help.
+ Check that the speed sensors and sensor rings for the affected wheel are clean and working correctly.
+ If there are problems with the availability of the system, the issues in the vehicle should be corrected
according to Guided Fault Finding.
+ Always make sure that addresses 812C and 0003 are functioning correctly.

+ Check DTCs in other control units and specific further TSB available (2078345) which are possible causes of
issues with the loose wheel warning in terms of the chain of effects or based on a message in the instrument
cluster.

+ Loose wheel warning and tire pressure messages are often a result of other issues with the vehicle, therefore
the main cause should be rectified first.
