Common Problems It Can Help Address

• Hard starting or drivability complaints tied to cam timing regulation

Installation Notes and Tips

Verify connector style, mounting location, and engine application before installation. Inspect the oil supply path, electrical connector, and related engine codes during diagnosis, since VVT solenoid concerns can be caused by contamination or wiring issues as well as the solenoid itself. Confirm fitment for 2002-2003 BMW 540i and 2002-2003 BMW X5 before service.
