Hva betyr feilkoden?
The engine control module adjusts the intake camshaft angle through adaptation when it sits too far forward, ahead of the crankshaft. The fault code is stored when the adaptation value exceeds a set limit.
Mulige årsaker
- Poor quality oil
- Intake camshafts are misadjusted
- The timing belt has jumped over some teeth
- A valve that sticks
- Mechanical fault in the VVT unit
Hva du kan gjøre
- 1Check the engine oil level and quality, and look for contamination
- 2Have a workshop check that the timing belt is seated correctly and that the camshaft basic setting is right
- 3A workshop can remove the intake-side reset valve and check the oil passages for dirt and blockage
- 4Replace the valve if it has stuck and cannot be cleaned
- 5If the fault remains, have a workshop assess whether the VVT unit is damaged
