If you like to argue - by all means - use whatever you like. You can argue with VW, through the dealer, to your hearts content.
I argued with my VW dealer they DID NOT use VW 508 oil at my first oil change,
they used Castrol 5W40 ( VW 502/505.01) and the engine didn't respond properly; I knew it the first hour I drove it.
I brought it back two months later and had them install Motul SPECIFIC 508/509 that I bough online.
They didn't refund my previous oil change though.
So They may be only "green dye" sensitive - -unless something catastrophically fails.
