I have a strange issue with my windscreen washer jets. It was working fine until a few days ago. The head light washer jets work fine but the screen jet just have no power and just about wet the bottom of the screen. I have checked the jets and they are clear and I have even disconnected the joint where the pipe splits in to two but or just trickles out of the pipe. Anyone had this problem before?

Yes, on a Passat about 5/6 years ago. I did what you’d said. Split the pipes, blew down each one, I had a partial blockage eventually blew it out (a pain) sucked the washer bottle dry, refilled and emptied it again, on 2nd refill all worked well. I did however about a year later need to swop out one of the jets, drivers side if I remember correctly.

I syphoned out the majority and bought a cheap syringe type thing with a capacity of about 1/4 pint.

I will try draining the washer bottle and see if that does anything.

It’s most likely the fine mesh filter on the pump. I’ve pulled and cleaned mine at least four times now.

Did you have to access it via the wheel arch to clean it?

Took the wheel and inner lining off to access the pump. The filter was glogged up so cleaned it out and replaced but it didn’t make any difference. Upon examining the pump it self it was extremely rusty so replaced it and all was back to normal.

Good to see you got it sorted, and thanks for posting the result and fix - so many people don't!
