because I already found many great things on the thick (and fixed
), I am superior to changing the hydraulic oil.First of all, I don't know what kind of stuff is in there and second, there's only the new hydraulic oil at VAG and I assume that this is synthetic. But I don't want to mix anything with others.
Did I look at the WE once what you could unscrew where to release the hydraulic oil.

I'd like to ask you how best to do this. My search in the forum didn't really yield much, so I hope I get some suggestions (as always).
