Ask them to talk to SA Bob in BMW service at Motor Werks in Barrington, Il. 847-381-8900.
I guess they can throw parts at it, but it is a software issue...well, for most of us with the window that rolls 1/2 way down on its own.
If it was the motor, the window would not move.....same as with a broken regulator. If my dealship has the software, why don't the others?
U am not Tech, but they are clueless.
