Parktronic Triggers Without Obvious Cause at Front Bumper
If you receive customer reports on the above model vehicles of parktronic triggering without obvious cause at the front sensors, no fault is stored in the parktronic control unit and the complaint does not occur when the front license plate is removed, this may be caused by the side edges of the license plate being detected as an obstruction by the PTS sensor. Due to varying license plate widths, the system may trigger at the front at random.
Note:
No additional license plate frame should be mounted on the front bumper.
Note:
The license plate width can be coded in Star Diagnosis as of CD 04/04 and on the following models:
All 171 models
All 211 models that contain Parktronic control unit with part no. A211 545 38 32 or higher
All 230 models that contain Parktronic control unit with part no. A230 545 26 32 or higher
In DAS version 04/04 or higher, follow steps below to program license plate width:
1. Information and Communication-->Parktronic-->Control unit adaptations-->Read coding and modify if necessary
2. Code the actual width of the license plate bracket.
