Final stage Oxygen sensor heater Oxygen sensor in front of catalytic converter Bank 2
NOTE
Separated plug connection = open reference-air duct.
Damage to oxygen sensor.
- DO NOT use spray, grease, fluid or similar products on the oxygen sensor plug connections.
INFORMATION
- Do not interchange the oxygen sensor in front of the catalytic converter with the sensor behind the catalytic converter as this will result in
implausible fault entries.
- The plugs themselves are coded and cannot be interchanged.
Diagnostic conditions

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.
INFORMATION
- 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: 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
