Default Audi put that in???
Looks from the picture that they put the wrong type of fluid in the brake line. That is what my old SS looked like after 140k miles on it, call them and have them put in OEM fluid back in. If that is not the case, maybe your pump is going bad?

that is the by-product of melting seals. It looks like you ran a fluid that your audi didn't like.??

I always wondered if it is particles of the master cyl seals and o rings.

I've never added fluid. Dealer did though.

Default Ick! Looks like someone at the dealer is going to get a slap to the back of the head!
If it's the seals being eaten away, I think I would be making my way to McGill!
