My '10 35d (diesel) did some bucking as I pulled out of the driveway yesterday and the CEL came on eventually. My OBD scanner showed code P2620 which is "Throttle Position Output Circuit Open" so I'm assuming there's something wrong with the throttle position sensor. It hasn't bucked since and the CEL is off now but I'm afraid this will eventually leave me stranded.

Anyone have any experience with this type of issue with their diesel X5?
