I had one as a temporary vehicle provided by Audi UK a couple of months back, (1.6 TDI 3 Dr SE S-Tronic).
Was actually pleasantly suprised by it. Engine seemed to be a good pairing with the gearbox and it was more than adequate for both town driving and motorway stints - even when loaded-up.
I only had one (albeit, minor) criticism being of of the gearbox specifically - at times the 7 speed S-Tronic could be a tad hesitant, notably when giving it the beans during the rolling approach to a roundabout, for example. I wouldn't let that put you off it, though.
