Mattie,
Looks like there are at least two grades listed for this (assuming it not on a long life sched?)
One of the main grades is indeed the 5w40 which i belibve is a synthectic based oil, the other (cheaper :lol: ) is the 10w40 semi synthetic type.
Both of these are listed as be being suitible for the VW501.01 & 502.00 vag recomendations.
