I have plastic creaking, clicking, rattling all over the place, from the passenger A-pillar to the dash under the airbag to the passenger B-pillar. The dealer insists that all of this is normal for my car since it has the sport suspension. They won't do a thing and claim there are no service bulletins for the 1-series relating to the cabin noises. I am trying to maintain some semblance of sanity.

Any tried and true strategies for getting the dealer to take action?
