The circuit board in the right rear has corroded beyond repair and the car has failed its MOT/WOF. Has anyone replaced these or made a repair? The search function on this site isnt working and the only repair I can find is for the LED in the rear quarter panel, not the tailgate.

Is there a part number catalogue anywhere where i an find the part number?

Ebay and Amazon have a part but its for a much later model (seems to be a very common fault on the newer cars).

heres a link to 3 pics
