Quick answer

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain subject vehicles, the engine control unit software does not correspond to current production specifications. The diagnosis routine for the pressure sensor in the crankcase ventilation system may be populated with incorrect data. As a consequence, the check engine light may illuminate after the engine is switched off even though there is no functional impairment. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the engine control unit software.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
