Rear washer leaking behind rear wheel arch. Located loose corrugated hose but can’t find what it attaches to once I peel back the wheel arch lining. Has anyone a diagram or photograph that could help please.

 

Try cleaning your rear washer first. Solved my problem.

@GavinC the best part about that video is “with minimal breakage and only one clip down the drain"

 

Mine was peeing on the driveway from the tiny nozzle that sprays the rear camera lens. Tried using a pin to see if the tube it was clogged, still leaking. Turns out it was a defective washer nozzle that the dealer replaced under warranty.
