In the A4/5/6/7/8 and the Q5 the AWD system is symmetrical (but the front/rear power distribution is not) so there's no torque steer. In the A3, TT and Q3/7 the AWD is not symmetrical since the A3, TT, and Q3 use a transverse engine layout and the Q7 uses a Borg Warner AWD system with an offset front differential. I don't know about the Q8.

I've had a few Audis and their AWD system is great. They're all really nose heavy though because the nature of the symmetrical AWD system pushes the engine really far forward as the front differential is integrated directly into the transmission.
