Temperature gauge is definately finnicky on hot, muggy days..
Also, the car is really loud when the fan blower is high. The AC works well, however I've notice a H2O drip that gets vaporized after turning off the engine on real humid days. I'm Thinking the cooling sys. is supposed to do that, no?
The drip is the condenstaion from your A.C. and is completely normal. In fact, if it is not dripping (outside, underneath where you have mentioned), particularly on humid days, then the water is most likely draining into your car somewhere.
I'm not overly concerned about the draining issue unless my H2O temp rises or water level falls. I would think this drip could wait for 7500 miles service, don't you think?

My only concern would be that you may have some water building up somewhere and mildew will start to grow in your system where water is never evaporating because of a pooling effect. I have seen this here in the Northwest and it is very difficult to eradicate. It fills a car with that musty odor that mildew brings. If I were you, I would have your dealer look at it sooner than later.
I assume you are not hearing any "sloshing" emminating from your dash. I guess the drain system in the A8s clogs easily and people have drained up to a litre of water out of their HVAC plumbing.
