Adjustment Intake camshaft Bank 1 to Cold start
- during Catalytic converter heating measure
INFORMATION:
- If only the fault for camshaft position timing after cold start is entered, particular attention should be paid to causes such as viscous engine oil or components that stick when cold.
- The catalytic converter heating measures take place for a limited time under certain conditions (cold start).
- This includes double injection, timing retardation, additional camshaft adjustment, ...
Diagnostic conditions
- Cold start with Catalytic converter heating measure
- then Engine speed 1,200 ... 6,000 1/min
- none of the following faults stored stored: P0010, P0020, P2088, P2089, P2092, P2093
Possible fault causes
- Dynamic driving style when oil level is near minimum (oil foaming)
- Engine oil pressure too low
-->(e.g. Oil thickening, Oil quality incorrect, Oil pressure control or Oil pump stiff / stuck)
- Solenoid valve, hydraulic camshaft adjustment stiff / stuck
- Camshaft adjustment stiff / stuck
- Intake camshaft stiff / stuck
Fault setting condition(s)
- Deviation Actual value - Nominal value Intake camshaft too high
