Intermittent fault

If the diagnostic trouble code (DTC) for this fault is stored but the adaptation value is correct, the fault is intermittent. The cause of the intermittent fault is probably a defective camshaft reset valve.

HINT: Faults may result from dirt in the camshaft reset valve. Try cleaning the valve.
