e93 headrest won't move up and down on driver's side

Just picked up my first m3 - 2011 space gray convertible. I love it.

One thing I noticed is that the electronic headrest adjustor switch (for up and down adjustment) doesn't seem to work on the driver's side seat. It works on the passenger side. I think I got it to move all the way up initially but now it won't move at all. When I click it up I can faintly hear the electric motor or whatever trying to move the headrest. When I click it down - nothing at all. All the other seat movement buttons seem to work on the driver's side.

Any possible explanation for this or quick fix? Or is this going to take a trip to the dealer?

Sounds like somethings busted. If you hear the motor one way it's probably not a simple fix like a fuse.

Thanks for the info. Seems weird that a newer, low mileage car would have this kind of electrical problem. Is this common? Or evidence of a larger issue with the car? Hope not...

Just in case anyone is interested, it was the seat module that needed to be replaced.

Seat modules don't just go, you must have ran over something...
At least that's what MelvinMrBMWBey says....
