Checking the status




- Start the engine and run it to normal operating temperature
- Read off and note the adaptation value for the camshaft at idle speed. The value must be between -8° and +8°.
The fault is intermittent if the adaptation value is between -8° and +8°. The fault is permanent if the adaptation value is lower than -8° or higher than +8°.










Continue - Checking components

Checking components
For the variable valve timing control to work, the engine oil must be at the correct level, of the correct grade and free of contaminants.
Check the level and quality of the engine oil. Check for contaminants in particular.
Adjust the camshaft settings.
