Probably not a specific part to the R but looking for a supplier of this part please. Will also check with Ash.
I just bought one from Ebay, part number on the fuse box is the same as the rest of the range or most of it, there is a prefix letter on the end of the part number, mine was "H", 1.9D was "J" not sure if there is any difference, didn't want to take the chance.
