well it is an all wheel drive car, i missed a shift years ago in my civic si, went from 2nd to 1st at about 8500rpm, tach went off the scale........ended up twisting the driveline side of the tranny shaft about 28 degrees, and that was in a little front drive car that weighed 2200lbs, suprisingly didn't bend any valves.....the audi weighs what? 3200? and it's all traction, and was said it stopped immediately....
i'll bet along with the engine something is REALLY wrong in there
