REPLACE OIL DIPSTICK; REPLACE CRANKCASE VENTILATION PRESSURE REGULATOR VALVE IF NECESSARY
This Service Campaign has been initiated because DAG has determined that due to increased crankcase pressure the oil dipstick may be pushed out of the guide tube. To prevent customer complaints concerning rough engine idle dealers will replace the oil dipstick on all affected vehicles during the next workshop visit. In addition, Dealers will also replace the crankcase ventilation pressure regulator valve on certain affected vehicles.
