Had these exact symptoms with a drive train malfunction error happen on my 2011 X3 (F25) four times:
1st time was a cracked air intake tube (induction charge pipe)
2nd Time was a faulty VTG motor on the transfer case
3rd time was a malfunctioning mass air flow meter
4th time was another cracked indiction charge pipe
The first one took 3 weeks to fix waiting for a part from Germany. All others were a couple of day fixes. In every instance except #3 they updated the car Transmission control unit (TCU) and DME software, but then it was the first model year for the F25 so they had lots to fix in software everywhere.
Good luck!
