Well it's peeing it down and there's a leak into the boot. Have tracked it down (I think) to the screw holding a rear light cluster in place put ain't got a clue what it's called or how to find new ones.

Is the plastic "screw holder" that pushes into the metal work, then the light goes on and it's the screw hold shown in the photo.



Any ideas what it's called / part number etc really appreciated. had bit of a panic when I saw a couple of litres sloshing about the spare tyre well.....it is called a well after all.
