Been trying to trace where the water gets in to the wheel well on my estate, think I've cracked it, at each corner of the rubber seal in the pic there's a small hole that lets water under the trim & into the well, took the inner panel off to expose two water lines from the corners direct to the well, dried everything off & refitted everything then went around under where the rubber lips over the inner panel with a fine bead of silicone, pressed along the rubber so it just oozed out the a wet finger to clean it up, seems to be working.
