The driver's side armrest is stuck in the upright position that we have. It moves back and forth very little, maybe an inch and a half to 2 inches. Is there a release button or something that can be pressed to allow the armrest to come down?

 

I think you might have a coin stuck in there. Your not supposed to put change in there for that reason. I got mine stuck on my A4 not too long ago because my dumb *** room mate put his change in there. You just have to fish out the coin with a screw driver or small pick.

 

Our 2003 A8L had the same problem, but we never put change in the armrest. I couldn't fix it so I took it to the dealer and it was a quick fix for them and they didn't charge me anything.
