Thanks for the replies guys, I really appreciate it. I'll get this stuff switched out as son as my filters get here next week. I think I'm going to try the Mobil ESP as others seem to get good VOAs from it.
Thanks again for the help.
Yes it is supposed to be using a 507 spec oil, but seeing how it is out of warranty and that there are many oils that likely meet 507 spec that aren't "approved", I figured I'd gauge what you more experienced users are doing.
But maybe it is better just to change it to be on the safe side...

I just picked up a Q7 TDI and am very new to diesels.
The dealership I bought the Q7 from (Chevy dealer) used Mobil 1 Delvac 5w-40 before delivery for an oil change. I am concerned because of the ash content. It's at 1.0 when I know most VW/Audi 507 spec oils...
