@flushm3: A little quick guide to replace the Throttle Valve Actuator. If you noticed that a check engine light would persistently reappear after clearing codes and when you shut the car off, the car would shut down pretty rough, this is caused by the Throttle Valve Actuator. Both 335d and x5d use the same part. The Pierburg is the way to go, OE part number: 700376040 #m57 #diesel #x5 #bmw #fyp
