I have a set of washers with pump and wiring, but they are designed to fit the small bumper model and sit proud of the bumper, so to speak, and are shaped to fit the ‘corner’. The washers on the ebay ad are flatter, with a slight curve at the edge, no doubt to sit on the top of the big bumper.
However, the small bumper washers do not fit the Country as the Bull Bar gets in the way. I have seen pictures (probably buried in one of my memory sticks) of a Country fitted with washers that were claimed to be OEM. Obviously, these are ‘flat’ type washers that sit further back on top of the bumper. I wonder if VW bodged the Big Bumper type to fit! I’ll have to check out my pictures!!
