# Service bulletin SC\-2022100016

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 \("MBAG"\), the manufacturer of Mercedes\-Benz vehicles, has determined that on certain Model Year \(“MY”\) 2013\-2016 E/GLK/GLE/M\-Class vehicles, the software for the water pump diagnostics may not correspond to current specifications. This issue has an extremely low rate of occurrence in the field and has no known emissions or fuel economy impact. However, in the rare instance this issue does occur in a vehicle, it may prevent the vehicle from passing certain state inspection requirements \(e.g., California SMOG check\). What We’re Doing MBUSA will conduct an Emission Service Campaign in which an authorized Mercedes\-Benz dealer will update the software for the water pump diagnostics on the affected vehicles.
