Camshaft Adjustment, Bank 2 - Above Limit
Diagnosis conditions
- Time elapsed after start-up greater than 5 seconds
- Engine temperature greater than -10 degree C
- Engine speed between 680 rpm and 6760 rpm
- No fault in camshaft adjustment output stage
- Reference mark OK
- No fault in camshaft position sensors
- No fault in engine temperature
Possible fault cause
NOTE: Solenoid hydraulic valve is not triggered, camshaft does not switch into late position
- Dirt in system
- Solenoid hydraulic valve mechanically blocked
Affected terminals

Diagnosis/Troubleshooting
Work Instruction 1:
Figure 1:
Figure 2:
1 - Voltage not applied yet, valve in output state
2 - Exponential voltage increase, magnetic field is built up, increase of the spring preload force
3 - Valve starts to move, spring force increases, valve reaches end position
4 - Exponential voltage increase, current limitation through selfinduction of the coil
