Bulletin Summary
Mercedes-Benz AG, the manufacturer of Mercedes-Benz, has determined that on certain MY 2019 A-Class (177 platform) vehicles, the engine control unit software may not correspond to the current specifications, causing the on-board diagnosis to incorrectly detect a fault in the lambda sensor that may result in the illumination of check engine malfunction indicator lamp (‘MIL’). MBUSA will conduct an Emission Service Campaign. An authorized Mercedes-Benz dealer will update the engine control unit software.
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.
