Bulletin Summary
Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain subject vehicles, the coding for the electronic ignition lock control unit does not correspond to the latest series production configuration. The electronic ignition lock control unit will be updated to change the logic for locking and unlocking the vehicle via the door handles. To unlock the vehicle, the large outer contact surface of the door handle must be touched. To lock the vehicle, the small, recessed contact surface of the door handle must be touched. MBUSA will conduct an OTA service campaign. Remote software updates are automatically downloaded and installed in the customer’s vehicle free of charge and do not require a dealer visit.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
