Rear wash problems 2010 s3

Rear wash has not worked for a while, then the wiper stuck in the middle. I have removed the wiper and motor and it was disgusting.*

I tested the wash with no wiper on and the water came out.*

I cleaned the motor, re greased it and put it back. I changed the*wiper arm*(as it had seized on and I damaged it removing it). I have also replaced the nozzle.*

But now the wash does not work. With the nozzle on or off no water. The connection in the boot when disconnected is wet and dripping so the water is making it down the pipe but not through the motor and up the spindle.*


Any ideas????

In my opinion, in 38 years of working on VAG cars, the 8P rear wiper motor is the singular most unreliable item I have ever come across. Almost every 8P you see on the road has a floppy or half mast rear wiper but I did a remap on a 2010 S3 yesterday and it worked..... it must have been a replacement.
