My girlfriend recently purchased a 2001 a4 quattro avant from her friend and we've already had to fix the wheel bearings, but we've discovered a leaking hose. We've been researching for a few hours now and it seems like it might be a breather hose, but we aren't having any luck finding a part or a diy tutorial Anyone have ideas?

Thanks in advance.

 

It's a crankcase vent/breather hose. Just undo each clamp and yank it out.
