This is exactly what's going on with mine. It's the b cable that connects to the back of the fuse box. When it happens I can reach behind the fusebox and wiggle the wire and it will make the car work. I have some info from another member that will help you SA diagnose it if this happens to anyone else.
It seems to be a newly discovered issue and a lot of techs are not familar with it. Creating painful trips to the dealership over and over.
BMW seriously needs to put out an SB on this. $3000 for their bad wiring is not right even if your extended warranty covers it.
Glad you got this figured out! It took me almost 4 weeks of my own trouble shooting to figure mine out.
