There are a handful of very active BMW forums, but I'm sure you know that since your practically a founding member of this board
lol
That all said...I have a bimmer FRESH out of factory bumper to bumper warranty and now into my CPO warranty. Big question is...Did you buy the BMW there? That goes a long way with regards to their compassion for your situation. If you push the issue nicely, they should cooperate, or very least only charge for the parts and no labor. ...at least they did for me at Tom Bush BMW here in Jax FL. Then again, they have bent over backwards and gone just plain out of there way to make me happy. No question that I will buy another BMW and I will buy it from them! I could go on forever about how great they are haha but I won't. As close to the warranty as you are...even a Porsche dealership would help you out.
