Rattles have been a big problem on my car. Infact mine went into the dealers yesterday and I don't get it back until Friday 24/10. Theres a rattle in the dash which they say is caused by a broken bracket and they need to remove the whole dash to solve it. They also have to remove the rear spoiler to replace the high level brake light which again has broken brackets. I have creaking from the doors which they say is where the door trim meets the headlining and may not be solvable. Last time it went in they replaced some of the rear seat fittings as they were rattling like crazy too. The dealer is rubbish but I'll persist until its right.
