Hmmm
OK, I've an idea.....
There is a Reset button on the front of the mmi box, so I'd suggest this first followed by unplugging the box completely and putting the car back as it was (don't screw things back together just plugs etc). Then start the iDrive system up as you would normally, then turn it off, lock the car and walk away for at least 15 minutes to let the car systems go to sleep.
Then replug the box back in as it should be and see it it then works. I'm hoping this will cure it, but it's certainly worth a shot anyway.
