So I searched and didn’t find a DIY on changing the oil in the wife’s 2021 A6 Allroad. Audi really doesn’t want you to do it yourself. No details in the owner’s manual other than take it to the dealer. Sticker under the hood at least says use 0W-20 & VW 508 00. But I have have no idea how much oil I need.

I’ve been changing oil for 35 years, so I doubt it will be that hard, but I always like to do my research first. Couldn’t find a DIY on YouTube either - at least not for a C8. Any help is appreciated.
