Emissions NCU - 2025030008
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
