Driving AWD with spare ok?
i need to get one of my wheels fixed and don't know if it's a good idea to drive even for a short while on my spare tire. i know having different diameter tires on an AWD is bad for the system but how much damage will i do driving for about 15 miles on the spare?

you'll be fine... just make sure it's properly inflated (60psi IIRC) and know you'll get a TPMS warning as a wheel/sensor is missing.
Just follow common sense and allow for extra braking time and maneuvering.
As w/ any car(w/o staggered wheel set up), rotate your wheels so spare is on rear axle not the front.

... more importantly, it's for safety.
The donut spare has a much different and smaller contact patch and likely material composition as well as tread depth, service rating, etc. than stock tires. All of which will adversely affect handling and braking. As such, you'll be able to maintain better control of vehicle w/ it on rear axle especially if it [pick any of the following]: hydroplanes, understeers, skids, blows out, etc.
