I have a rear wheel rotor that seems to be getting too hot.. Is this a common problem? Does this car have floating calipers that sieze? After a 200 mile drive, the wheels seem to be coated in brake dust. Doesn't seem normal to me, but I am unfamiliazr with the car. Car has 88K miles. Has anyone noticed the rotors getting pretty warm after short drives? < 4 miles?

Do you use your parking brake? If so, it's not releasing.

If not, your caliper is sticking, probably from a torn boot on the caliper, maybe from this procedure here:

Versus using the brake tool shown here:

If that is the case, you'll most likely need a new caliper unless you can find a rebuild kit and somebody to do it.

a caliper issue. Audi parking brake cables can get road grime and corrosion into them and stick in the engaged or partially engaged position. Could also be an adjustment issue with the parking brake cable. Let us know what you find.

Even after a 4 mile drive, the rotors do get pretty warm. The pads never completely pull away from the rotors (or you'd have too much free pedal travel when you go to reapply the brakes), and even the very slight drag heats the rotors.

You still may have a problem, though. After a long 200 mile drive, it's not unusual to see the front wheels coated with brake dust, but you should expect to see much less at the rear, and the left and right sides should be the same.
