Just bought a silver 2001 Audi TT 225 Quattro Roadster with the baseball optic leather interior and all that good stuff. A little bit of a step down from my previous car, in terms of speed, but at least I gained a turbo, all wheel drive and a droptop. It's a bit rattly due to the year and 93k mileage but I still love driving. Only thing that worries me is that sometimes when I am stopped the RPM's drop below idle for a second and then come back up almost as if the engine is trying to shut off. This goes away after I drive the car for a minute and also conveniently started happening after the test drive. Any ideas on what it could be? Info display on the dash is a little burnt out too.
