I had the same issue on my 2007 750i my problem was on the drivers seat. My wife would gloat and tell me how comfortable her side was, drove me wild. Luckily my car still has a few months CPO so I had BMW check it, it was covered and fixed for $50 deductible. Now I have it I never use it and my wife has stopped gloating suddenly....was she pushing my buttons?? Incidentally at the same time I had my dealer check (and repair under CPO) the steering telescopic motor, the wheel went up and down but not in/out. That was another $50 well spent dollars, since then I have thought about the steering mechanism and how it might have got broken. I hasten to add it was not working when I purchased it. When you switch off and exit it is tempting and convenient to grab the steering wheel to assist exiting. My feelings are that often the steering is still "in motion" and grabbing the wheel might place undue strain on the components. I wait for all movement to cease and even then resist clutching the wheel to aid my exit....just a thought. My dealer spent a lot of money on this repair as it was not just the motor but also they had to replace a shaft.....
