Yes. AWD is harder on the clutch. The A4 is also pretty heavy. If it's a contest between the tires loosing traction and the clutch slipping, I know from experience that you're gonna slip the clutch, those tires grip hard. I mean, HARD. Anyways, the clutch is pretty well balanced though, stiffest of any car I drive today but I grew up driving a 5-speed 4x4 95 Chevy Blazer V8. Wish I had convinced my dad to keep that car instead of buying the Nissan Frontier he got, that thing was a beast. Clutch was bad when we bought it so we got it cheap, I drove it with the bad clutch till he thought I was good enough that I wouldn't tear up a new one. Guy at the tranny shop that did the clutch swap stalled it six times driving it into the garage, had to finally ask me to do it. I was a 15 year old kid at the time and he was a 40 year old man. Ever since then, clutches have all felt like cake to me, . AWD is definitely gonna make it a tough adjustment if you're used to driving a much lighter stick, but I really don't want to recommend to you that you get ANY kind of Automatic Gearbox.

Also, to BlkCD5's point, there are plenty of electrical problems on older A4's. The newer the A4 the less problems it will have over the long run, they kept fixing bug after bug as they got the chance. *shrug*
