I have a 2000 Audi TT and I notice quite a strong smell of fuel/exhaust when the top is up and in slow traffic. I've been under the car and can't find any leaks. Does anyone else have this problem?

 

I had a similar problem with my 2001 TT. The car was smelling of fuel. The reason in my case were the 2 rubber fuel tubes that are sending fuel to the engine. I got them replaced (very cheap and easy fix) and everything was ok

 

Great advice. I'll certainly have that checked out.
Thanks.
