Hi all ive tried (with not much success) to find a specific thread to the A4 Avant rear washer jet inop issue. ive filled the washer bottle, unblocked the jets and you can hear the pump operating and still no water. can anyone give me an idea if its likely now to be a waterpipe connection issue and where its likely to or where its common to leak from/to? anyone know how to remove the tailgate trim (where the warning triangle is housed) as well as im thinking it could be a pipe connection issue there, but that said i cant see any water anywhere. thank you in advance.
