Hello everyone, I have a little problem, I drive a 2.0TDI Audi A3 from 2006. Now I have just seen that behind the brake as well as the inside of the rim everything is full of something oil-like. You can not wipe it away with a cloth, it only smears. It is sticky and dark to slightly greenish. I first thought about oil, but it is too thick for that. Hard to describe. Anyway, it is so much that the “inner” rim bed is completely covered, you can see the silver of the rim in no place. In addition, all small stones stick in it. Also behind the brake disc or the cover plate and around the axle cuff everything is fully covered, that one can no longer see the material under it. Can this, with the quantity, be the fat from the axle cuff? I should drive tomorrow morning 400km, I would only hate that if it is the Manchette. With the crowd there can not be much left in it anymore ??
