Quick answer

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (MY) 2009-2012 GL-Class, ML-Class, R-Class, and S-Class (164/166, 251, 221 platforms) vehicles, the coding for the engine control unit does not correspond to the specifications as part of the BlueTEC update diesel field measure (aka Emission Modification). This could result in the VIN number not being read out from the vehicle. This could affect the vehicle smog check. MBUSA will conduct an Emission Service Campaign in which an authorized Mercedes-Benz dealer will update the SCN coding for the engine control unit on the affected vehicles.

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.
