Rotors
Have 5k miles on my 2.7, and knew from the first stab of the brakes that the rotors were for ****e. Replacements are backordered. I'm coming from a BMW 330 - now those were brakes. Also have a distorted windshield, though not too bad. Anyhow, it's nice to get the info from this site before confronting service.

Re: Rotors
Both are well known issues. I had my front rotors replaced after about 8K (noticed vibrations during a trip to the Grand Canyon...long downhills at abot 80 mph, slight touch of the brakes set of vibes, almost as though ABS was kicking in.)
I have read on this forum about the windshield distortion. Many had it replaced under warranty. Audi is certainly aware of it. Have yours replaced.

Re: Rotors
When I hit the brakes with moderate pressure there's a very noticable vibration felt in the pedal and to a lesser extent the steering wheel. Doesn't really shake the car, but it's not right, certainly not on a 45k car.

Both known issues and owners have had difficulty correcting either.
Many owners have had windshield replaced with one that's even more warped. Part of the problem seems to be that the install process itself can create the distortion. Many, myself included, have elected to live with distortion that isn't problematic.
My rotors ('01 2.7T) give the impression of being warped, BUT NOT ALL THE TIME. Something else is obviously going on. The brakes work great, and it doesn't bother me enough to ask the dealer to work on it. Some rotors have developed high rust spots from being stored, and owners have had those corrected either by replacing the rotors, or burning them off in high speed brake applications, and/or driving in reverse and applying them with vigor. Mention this, as you might want to give it a try before resorting to replacement.

Re: Rotors
i had my rotors replaced at 16000 miles bc they were warped.
now im at 25000 miles and they are warped again...the dealer ordered new ones for me but i havent had the chance to get them installed.
btw...all this was done under warranty.

Re: Rotors
This could be a couple of things. Either you are using your brakes alot, or not enough.
Without a doubt the 2.7t with the HP2 calipers (2000 and 2001 model years) are notorious for warped rotors. The rotors get too hot. This could be your problem, however it usually only shows up on cars that have heavy, sustained brake usage, like at a track event.
The other possibility is that you are too gentle on them. Large diameter rotors, like the ones on your car, need to be used. Deposits can accumulate on the rotors and or pads.
My suggestion is to go out and do a few 60 to 0 stops using threshold braking. Keep doing it until you can feel the brakes starting to fade. This should "clean" up the rotors and pads. If they still vibrate after that, the rotors are warped.
I had this problem at about 5K miles. I did my first track event and it "cleaned" them up and they worked great. During my second track event I got them too hot and warped my rotors and chunked my pads.
I've solved this problem, hopefully, by going to 2-piece Coleman rotors. They have much better cooling capabilities and can handle the heat much better.

Did the "first stab" actually warp them, or is the problem something other than warping?
I've got 11K and have had no problems.
My first few hundred miles, I found the pedal to be very spongy. I suspect that I have adjusted to the pedal feel.
If you can live with the windshield ripples, do so. History suggests that the fix may be worse than the problem.
