Im a new owner to a 2001 a4, and am still under the warranty from the dealer so I want to get all of the problems fixed asap. Lately there has been what almost EXACTLY resembles crickets chirping when i start the car and put it in first, then drive in first and into second. Seems to go away at third. The feel of the car hasnt deteriorated, but my theory is that any unnatural sound sounds like a big buck repair in a little bit. Anyone got any ideas?
