No, 0Wxx and 5W40 are available in syn only.
I cant remember what Audi called for in terms of Oil change timing, but if they allowed you to stetch it out a bit, I would use the castrol 0w30 in a heartbeat in that car.
I wouldnt stray too far from what Audi recommends. Nice car BTW, just play within the rules.

Pep Boys has Free Peak oil + Proline oil filter after rebate, I wold use Peak 5W30 for short interval such as 1-2k miles then using good synthetic oil 5W40 in summer and 0W30 in winter after that.
It came with GC, the only 0w30 to meet VW 502 spec.
Normal thin 30 weight will not do in that engine, except in the coldest cold.
I'd do a run of Auto-Rx and use 10w-40, unless it burns oil, maybe 15w40 in summer unless you do mostly short trips.
Trip length and cliamte are the two factors. Any 5w-40 will do if you want synthetic oil, but it is definately not needed. The most common 5w-40 is Syntec, but I am not fond of it. Look for Shell Rotella T synthetic 5w-40...that's one of the best otc oils for that car, but really...conventional 10w40 like Pennzoil or Havoline is fine up to 5000-6000 miles.
AVK engine does have it's problems though. I would not skimp on the Auto-Rx.

What does the other two cars have to do with this one?
My wifes 97 Jetta just starting using 10W40 Valvoline. The valvetrain has quieted down much better. Before that it saw nothing but 5 and 10W30's.
The owner's manual says otherwise.
If you like to use thinner oil, 5W20, in your new Audi then give it a try.
My '00 MB E430 had Mobil 1 0W40 (MB recommended) all its life until 90k miles, last spring I changed to Pennzoil Platinum 5w20 and the engine is so much quieter than with thicker oil, gas mileage increased about 3-5%. After about 5-6k miles the oil is so black I changed to Delo 15W40 and the engine is about as noisy as with Mobil 1 0W40 and gas mileage went down even worse than Mobil 1 0W40.
I changed oil last Dec to Mobil 1 0W20 and engine is quiet again and gas mileage went back up similar with Pennzoil Platinum 5w20.
Since most of the trips are less than 10 miles, the oil is rarely reach operating temperature so that thinner oil is better.
