VW 503 is the low HT/HS LL-spec, ex:Castrol SLX II and it might damage a normal engine, think 5w-20.
VW 503.01=normal HT/HS LL-spec, ex Castrol SLX or GC. Similar to MB 229.3
VW 502 is based on the older generic A3-spec, under $2 oils meet it, so does Belgian Syntec.
Oil Specs for VW/Audi Gas Engines:
VW spec HTHS
502.00 3.5
503.01 3.5 Longlife Service
503.00 2.9-3.4 Longlife Service
505 range is for various diesel applications.
