Retrofit Adapter Wiring Harness on Camshaft Adjustment Solenoids
Revision/Date/Purpose
This Service Campaign has been initiated because Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that due to the
settling properties of the seal, oil may leak from the camshaft adjustment solenoid. Dealers will retrofit four adapter harnesses onto the engine wiring
harness as a precautionary measure at the next workshop visit

^ Please review the entire Service Campaign bulletin and follow the repair procedure exactly as described.
Please note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.
