Wife's x5 had a parasitic drain ended up being the "hedge hog" FSU blower resistor pack. Possibly the first repair I did on her car. It was intermittent. Just occasional dead battery. Figured out the problem using xoutpost of course. I think there is a fuse you can pull to eliminate the circuit to make the determination.

My DMM will record peak current over up to 24 hours see if yours will. Did you disconnect the battery neg terminal to run the current through DMM or have a DC clamp meter?
