I had a blocked pipe but coolant now flows and leaks out where it joins the rear pump - due to the 'o' ring missing. Unable to confirm what size the 'o' ring is I've bought a small set of 'o' rings from China. Have tried a few but then no coolant comes through, so it's obviously an 'o' ring problem. Maybe I need to get the 5JO 955 871 A coupler set as that comes with the infamous 'o' ring. I have an MOT due but it's not part of the MOT the rear wiper, so I will fix it as and when.

I've got this issue but have cleared the pipe going to the motor and screen cleaner is flowing - however, I've lost the 'o' ring so it's not sealing or fluid getting to the motor. Does anyone know the 'o' ring size please and where it goes on? Does it go onto the black nozzle that the pipe connects to? I only ask as I'm sure the 'o' ring was down the 'pipe going to the motor' when I first looked into it. Not sure if that's the right place for the 'o' ring though. Thanks
