Camshaft Profile Actuator A Stuck Bank 1
2001-2005 BMW 325i E46 2.5L I6 🇩🇪
Description
The camshaft profile switching actuator for Bank 1, intake side, is mechanically stuck in one position. Multi-profile camshafts switch between low and high RPM cam lobes.
Symptoms
- Check Engine Light
- Loss of high-RPM power
- Rough idle if stuck on high cam
- VTEC/VANOS-like system not engaging
- Engine sounds different at high RPM
Common Causes
- Oil sludge blocking actuator passages
- Actuator solenoid failure
- Low oil pressure
- Worn actuator pins or springs
- Incorrect oil viscosity
Diagnostic Steps
- Check engine oil level and condition
- Monitor camshaft profile PID on scan tool
- Command profile switch and verify response
- Test oil pressure at actuator feed
- Inspect actuator screen for debris
Repair Notes
Flush engine oil system. Replace cam profile actuator solenoid. If pins are worn, camshaft replacement may be needed.
