BMW and electronics... a bad marriage ...I had this problem too, car was at dealer for a full week. They reprogrammed 21 modules, including the so called footrest module, which they thought is the cause of the frequent wakeups. Sad to say that after 4 weeks, I had the problem again. I did not ask them again to have a look at it since I need the car to go to work.

Now I have again issues with electronics (dynamic drive failure). At this current rate of failures, I can drive the car for 4 weeks and then have to bring it in for fixing all the issues...

Sad ...
