09 X3 power drain, baffling 5 mechanics

[krautcars]

Ok so I am wits end. E83 can't find power drain and measuring current flow on negative terminal with voltmeter I have:

pulled all fuses
checked alternator and starter
pulled amp plug
hunted for potential key if under seats
replaced fan at stereo faceplate

It's baffled 5 mechanics and myself and I have no idea. Maybe a module is kicking in. I am open and grateful for any ideas. I need to sell this pos 7 months ago but cannot fix this.

How did the techs check for the power drain? Did they connect a digital amp meter in series with the battery’s negative cable? What is the typical reading? Anything above ~70ma (0.07 amps) is considered abnormal. Have the techs properly tested the battery? How old is the battery? Did they disconnect the main power cable from the alternator and the starter to check the current flow? Did the disconnect the cable that goes the fuse panel from the jumper post located under the red plastic cover under the hood to check current flow? Has the car been in an accident?

Yeah if a battery draw has 5 mechanics baffled, then you need to find a real technician, and not a mechanic. Lol
