GD rear washer check valve
« July 31, 2021, 16:16:03 »
When the rear washer on my 2015 car stopped working, even though I could hear the pump working, I suspected the check valve was faulty. Unlike the FD where the check valve is concealed under the roof lining, the GD has the valve conveniently located where the hose crosses over the hinge line at the tailgate. All that is required is to pull the hoses off the valve. The end of the valve has a yellow insert, I pulled this out by pushing a round needle file into the bore and pulled it out. Inside is a spring, a piston, and a rubber seal which locates onto the end of the piston. There seems very little to go wrong, but it can stick and stop the water getting through. I re-fitted the valve body to the hoses without any of the internals and the washer works fine.
