ok, after some searching on the net, this is what I found:

from which I got this info)
List of the most common VW standards
VW 500.00 – VW spec for multigrade engine oils for petrol engines with SAE 5W-X/10W-X viscosity for engines built up until August 1999 (MY 2000).
VW 500.00 + 505.00 – Oil meets both VW 500.00 and 505.00 spec.
VW 501.01 – VW spec for petrol engines for engines built up until August 1999 (MY 2000).
VW 501.14 – Brake fluid with low viscosity, VW 2006>.
VW 502.00 – VW spec, oil for petrol engines. Successor of VW 501.01 & 500.00 spec.
VW 503.00 – Long-life petrol engine oil for VW cars with WIV. Meets ACEA A1, SAE 0W-30 or 5W-30. Suitable for the AUDI S4, engines with an output greater than 180bhp should use 503.01 or 504.00/507.00.
VW 503.01 – Special engine oil for some VW petrol engines. SAE 5W-30. Suitable for the Ausi RS4, TT, S3 and A8 6.0 V12.
VW 504.00 – Long-life petrol engines with WIV.
VW 505.00 – Passanger car diesel engine oil, minimum performance level CCMC PD-2. Lists viscosities:- SAE 5W-50, 10W-50/60, 15W-40/50, 20W-40/50 requiring 13% max evaporation loss and SAE 5W-30/40, 10W-30/40 requiring 15% max evaporation loss.
VW 505.01 – Special engine oil for VW turbodiesel with pump-injector-unit and for the V8 commonrail turbodiesel engines. Meets ACEA B4 SAE 5W-40 spec.
VW 506.00 – Special long-life engine oil for turbodiesel engines with WIV, viscosity is SAE 0W-30.
VW 506.01 – Special long-life oil for turbodiesel engines with pump-injector-unit with WIV.
VW 507.00 – Long-life diesel engine oil with WIV.
VW 508.00 – Fuel economy low saps oil in development.
(WIV is extended drain periods up to 30,000km or 24 months.)
So I guess the B8 S4 should be using 503.01 or 504.00/507.00?
What does your manual say? (my car's only coming in November)
