I use german castrol in my Rabbit 2.5. All 2005 and up VW's need synthetic oil. Receipts with oils other than synthetic will void the warranty, however. Again, it does not NEED to meet 502 spec, butyou need oil change receipts with mileage documented. A good idea is to buy oil filters from the dealer and have a service manager document the mileage on your order and sign it.
I went to my dealer and asked for oil for my 2002 VR6, synthetic. They offered me a bottle of Castrol Syntec 5w30. It is not on the approved oil list. So I would agree with you.
