RE: [bmw] 2002 X5 3.0i "Service Engine Soon"

["Brian Kearney" <briank@xxxxxxxxx>]

>>>>Tonight as I was idling in park outside of a store (waiting for my
wife),
the "Service Engine Soon" light illuminated (not flashing) and then the
engine began to idle "rough" and felt as if it was going to stall. We then
drove home (a few miles) but there was noticeable loss of power; as if one
of the cylinders wasn't firing.


I think it could be a throttle valve. I had a similar problem with mine,
although my throttle body is a Dinan, but almost exactly the same symptoms.
Mine happened when the ABS kicked in once. Did the OBC read "Fail Safe
Mode?" The dealer replaced it, and its been fine since.
