Summary

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that the software for the engine control unit in the subject vehicles may not meet current specifications. As a result, the diagnosis for monitoring the air fuel ratio might not be activated in low load operation as intended. Consequently, this may not meet local regulatory requirements for on-board diagnostics and/or exhaust gas emissions. An authorized Mercedes-Benz dealer will update the Engine Control Unit software in the affected vehicles.

Owners of these vehicles have filed 4 complaints in the engine category.
