So my rear washer b6 avant packed up, i filled the bottle but nothing coming out. Right I think, I wonder if this is like my SEAT leon where the pipe fitting blew in the sill. So i give it a long squirt and next there is fuid pouring out the tailgate. A quick net search later transpires this is a common failure. I cant believe how inept Audi is in not dealing with this problem in the vw audi group, a quick bodge with zip ties after a total PITA removal of the rear trim and its fixed until the next joint blows I guess.
