Bank 2 counterpart to P1340. The cam-to-crank relationship on bank 2 (cylinders 4-6) is out of position, indicating cam-timing deviation. On the M96/M97 this typically stems from VarioCam wear and cam-chain stretch on bank 2.
SYMPTOMS
- Check-engine light
- Rough running
- Power loss
- Cold-start rattle
LIKELY CAUSES
- Cam timing deviation from worn VarioCam components (bank 2)
- Stretched cam chain
- Failed tensioner/guides
- Sticking oil-control solenoid
- Cam/crank sensor or reluctor fault
DIAGNOSIS STEPS
- Compare commanded vs actual bank 2 cam angle
- Check oil and solenoid operation
- Inspect chain/tensioner for wear
- Verify sensors/reluctors
- Mechanically verify timing if deviation is large
RELATED PARTS
- VarioCam actuator / wear pads
- Timing chain / tensioner / guides
