You should have one. Sits on the drivers side fender well right behind the air box. #15 in this diagram. Some have said these can fail but they usually make noise first.

Thanks Overboost. I may not have heard the pump fail as I have only owned this for about 10 days. It may have died before I took ownership. Would this be the cause of my no heat when idling situation?

The thermostat may soft-fail (open too early).
Or your WP may be bad (impeller fell off) etc. At this age/mileage, search forum for cooling overhaul.

The soft fail thermo could be the problem too, is there any way to check without replacement? I know they are pretty inexpensive to replace but are there any other symptoms, like extremely long warmup time? Or running too cool?

Have you unlocked the BC hidden menu and monitored the KTemp (#7)?

wpoll, nope and have no idea what that is... I guess I'll do some more searching! What am I looking for once I start monitoring this temp? Thanks again, BTW.

BMW X5 - Access the Hidden Onboard Computer (OBC) Functions. *edit* note that this info (linked above) contains an error - you need to add all FIVE digits from your VIN (not four as stated).
