Service bulletin LI54.30-P-080709

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Complaint Display message in the instrument cluster for "Active Brake Assist Inoperative" or "DISTRONIC inoperative". AND Fault code C1100FC or C1100FD is Active or Active and Stored in MRR_F_Gen6 (B29/20). Cause The holder for the MRR_F_Gen6 (B29/20) front radar sensor may no longer have the correct alignment (angular position). Remedy Confirm whether the instrument cluster message was already present upon receipt of the vehicle by the end customer. Check if DTC mileage was present prior to vehicle PDI/Sale of vehicle. In this case, submit under warranty with the specified SSL. If vehicle exhibited the instrument cluster message AND DTC mileage was AFTER customer hand‑over, cost settlement under warranty is not possible as it is due to outside damages. Note: Additionally, it is possible to obtain a timestamp for a possible collision, including the date, if the end customer has purchased the "Parking and Collision Alert" digital service. In both cases, the front radar holder must be replaced. After replacing the radar holder, perform calibration in IDC_Gen6 (N62/5).
