It could very well be a stuck thermostat. I had the exact opposite problem.
I couldn't get the car to heat up. The temp. gauge was always on the cold
side. My thermostat was sticking open.
Unfortunately, on the V6 Audis, the thermostat is underneath the timing
belt, so its not an easy DIY replacement. If you are anywhere near 60k, do
the timing belt service now and change the thermostat while it is out.
Good advice for anyone else doing their timing belt... don't forget to do
the thermostat at the same time. That $25 part will cause you a lot of
hassle if you don't replace it and it fails.
