Thanks for that info guys. There are always discussions about official VW approvals for 506.01 (as opposed to the oil maker claiming their oil "meets/complies/exceeds the standard"). I guess if the VW approval process was cheaper/less complicated more oil manufacturers/blenders would bother to jump through VW's approval hoops.
I'm guessing that now that all new VAG TDI engines are designed for VW 507 that there will be less incentive for oil manufacturers/blenders to continue to make 506.01 in the future.
Quite a few people believe that VW 507 is OK for the few engines where 506.01 is specified, but if you have an older R5 engine and are a stickler for following the handbook (ie 506.01) your choices are likely to become more and more limited (and probably more and more expensive) as the years pass.
