Bulletin Summary
Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that the software for the engine control unit in the subject vehicles may not meet current specifications. As a result, the diagnosis for monitoring the air fuel ratio might not be activated in low load operation as intended. Consequently, this may not meet local regulatory requirements for on-board diagnostics and/or exhaust gas emissions. An authorized Mercedes-Benz dealer will update the Engine Control Unit software in the affected vehicles.
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.
