Are all VW504 oils 5W-30?

By accident, I got Euro owners manuals in German when I picked up my RS4 in Ingolstadt. I know enough German to read that they recommend VW 504 00 - spec oil. There is no mention of viscosity required...only VW 504 00. No mention of special RS4 oil, or of VW 504 in 5W-40.
The only ones I see, online and in European stores are in 5W-30. Are they really specing 5W-30? Does it actually say 5W-40 in the US manuals?
I've read about other oils being better, but I want to stick with proven VW-specs to avoid warranty problems, and because I know the specs and the related tests are there for a reason..even if I'm in the minority. Let's just say I know a bit about oils and testing even though I'm not an internet celebrity.

My dealer uses Castrol Syntec 5W-40, which is what I use for topping off as well. Mobil 1 5W-40 is the only other oil I can find at local retail outlets that meets the 502.00 spec.
You'll get all kinds of conflicting recommendations here. RI RS4 recommends some kind of whale *** oil or something.
