For variable valve timing control to operate correctly the engine oil must be at the correct level, of the correct quality and not contaminated.
Check the engine oil level and quality. Check for contaminants in particular.
If this diagnostic trouble code (DTC) is stored, the most likely fault cause is one of the following:
- Camshaft belt incorrectly seated
- Incorrect basic setting for the timing belt
- Faulty camshaft reset valve (the slide in the valve has stuck).
Hint: First try adjusting the basic setting of the camshaft. Then read off the camshaft discrepancy at idle speed with the engine at operating temperature. The normal value is 27°CA (+/-8°CA). If the value is incorrect when the basic setting of the camshaft is correct, try cleaning the camshaft reset valve.
Note! The camshafts must be adjusted using the adjustment tool for the camshafts and crankshaft in the prescribed manner.
Try a new camshaft reset valve if the above fault-tracing does not remedy the fault.
Remedy as necessary.
Hint: The fault can also be caused by a damaged variable valve timing unit. The variable valve timing unit may be damaged if the above fault-tracing and corrective action do not remedy the fault.

Hint: After carrying out the repair, check that the fault has been remedied.
In order to verify this diagnostic trouble code (DTC), adaptation of the camshaft must be completed. Adaptation of the camshaft is carried out by the engine control module (ECM) when the catalytic converter is warmed up, during engine braking (fuel shut-off) above 1300 rpm for at least 10 seconds.
Caution! Test must be performed on a road with minimal traffic. Ensure that applicable traffic regulations are conformed to.
- Start and run the engine for at least 30 seconds
- Drive the car on the road. Ensure that the conditions for adaptation are met: engine braking (fuel shut-off) above 1300 rpm for at least 10 sec. The conditions can be satisfied for example by driving the car with a high engine load up to approximately 90 km/h and then releasing the accelerator pedal for 10 seconds. Repeat the schedule to ensure that the adaptation is carried out.
Note! In order for the adaptation to be carried out, the accelerator pedal must not be touched during engine braking.
- Read off the camshaft adaptation after driving.
Check that the value for the camshaft adaptation is correct. The value must be 27°CA (+/-8°CA).

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
