PDAGLACKHA2024-01-29. Service bulletin. EQUIPMENT; STRUCTURE; VISIBILITY. Mercedes-Benz AG has determined that on certain Metris (447 platform) vehicles, the fuel pump impeller might not meet specifications in regards to material characteristics. As a consequence, the impeller might deform. It might therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, and increase the risk of a crash or injury.
