Easy now it's only my carpet😀 I've recently bought an a4 avant 2009 . Not my first Audi and I'm not too bad with the spanners. I've noticed that the windscreen washer fluid ( I can smell the fluid) is getting into the passenger foot well, now I don't know if it's all the time or only when I operate the washers. Can anyone give me a hint on the route of the rear washer pipe or any other ideas.

Hi Alan....welcome to the Forum

Sorry, don't know the exact routing of the washer hose but I wonder if you could disconnect it from the pump and introduce compressed air into the line to see/hear where the hole is.

Let us know how you get on with it all
