You know i have the same smell and mine is an 06 and you know i just took it in for the 45,000 tune up and they didn't catch it or they didn't want to do the free work ( sorry i've had trouble with warranty work before and i'm not a fan of it). I also want to say thanks for the link for the TSP's you know i've had alot of those problems listed but because i didn't know they didn't tell me about it so it resulted in a lot of money dumped into a new car. I've had my 5 for 2 years now and don't get me wrong my wife and i love the car but it has cost me alot of money. After my first thousand dollar fix ( squeak or knock in the suspension) i decided that it be best to become a Mechanic to save me some money and help out people instead of rapping them. and a good thing about the TSP's is it pretty much tells you how to do the work so thanks.(rockon)
