Has anyone else had this problem? I can hear it moving around when I open the boot. It slowly drips down the left side channel of the boot, from the petrol cap area, and has stained the rear bumper.
I can't see how the water is getting in, and I can't see how to get it out!
Most likely the two skins that are bonded together to make the lid have split open .. usually along the edge closest to the rear window. Closing the lid onto the seal forces the gap apart slightly where it's split ..
