The box does say covers most VW's Audis sold world wide since 1990
I copied and pasted from your post and had a look at the VS450.
I wasn't sure if the unit covered just diesel engines/error codes or all engine types.
Not sure whether to buy from Ebay or Amazon,, there is all ways the slight worry of buying a fake off Ebay.
