Thank you for info on parts places. Was able to get dealer to buy the motor, and I cover the install. Now another issue. This all happened at the same time. Got a "selflevel susp.inact" message, both front seat heaters stopped working, the seatbelt audio and visual warnings keep going even with belts secured and a sevice engine soon with codes for a 3:6:8 cylinder misfire. In addition, central locking button sometimes works, sometimes not ... and without warning the alarm system goes off and doors won't open until car is shut down. Are there issues with X5 computers going fritz with lots of sensors etc showing problems. Can't believe all went wrong at once. Great car otherwise. We have a beautiful 1998 323i that has never acted up like this. The X5 is a 2005 4.4 with 105K miles. Any thoughts?
