I'll type this in slowly so that even the more intellectually challenged, European Forum members can understand it....������
The Amsoil 5w-30, European Formula IS on VW's Approved List for VW 504/507
The Amsoil 5w-40, Classic European Formula IS on VW's Approved List for VW 502/505.00
The Amsoil 5w-40, Mid-SAPS European Formula is recommended for VW 502/505.01, but is NOT on VW's Approved List
The Amsoil 0w-40, Classic European Formula is recommended for VW 502.00/505.00, but is NOT on VW's Approved List - even though it has the same additive chemistry as their 5w-40 that is approved for these Apps (that's strictly a business decision, since the 0w-40 is fully PAO based, and so this would require duplication of all the engine tests)
For what it's worth, the 5w-30 and the 0w-40 have the best extreme temperature properties of these four oils and would be my choice if you want to stick with a VW Spec oil. However as I previously mentioned, the general consensus is that the latest API Spec, HD diesel oils (current "CK-4/SN" ), will work even better in older TDI Motors not requiring a low ash oil. This is particularly true of the PD engines which really need an xw-40 oil, the thicker the better (in terms of HTHS viscosity).
