Update the Selective Catalytic Reduction (SCR) Control Module Software

This Service Campaign has been initiated because Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that the SCR Control Module Software may not meet current specifications in the subject vehicles. This software update will correct a condition of a low level indicator when sufficient AdBlue remains in the tank. Dealers will update the SCR Control Module Software at the next workshop visit.
