Quick answer

An authorized Mercedes-Benz dealer will update the engine control unit software.

What this bulletin may mean before buying

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.
