Update Transmission Control Module Software

This Service Campaign has been initiated because Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that the transmission control module software does not correspond to current production configuration. Low transmission oil temperatures combined with certain driving patterns may result in customer complaints about engine running characteristics. An authorized Mercedes-Benz dealer will update the transmission control module software at the next workshop visit.

Prior to performing this Service Campaign:

Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
Please review the entire Service Campaign bulletin and follow the repair procedure exactly as described.

Approximately 640 vehicles are affected.
