Hi everyone i am owner of 2017 superb 

2 days before my windscreen washing system stopped working 

When push washing arm not coming any voice from pump

İ check pump fuse (f42) its normal

But i can not find this pump relay is which one

Please help

Does the rear wash work?

 

If it does then it’s 100% the pump on the washer bottle itself and 2 way valve broken

 

Then all you need to do is remove wheel and wheel arch liner and replace

Thanks for your repply my car doesnt has rear wash

System dont has any relay?

Not sure about relays

 

Does your car have xenons? If so keep activating the washer and see if the headlight washers work.

 

If not it’ll probably be best to take wheel arch liner off anyway and get testing with a multi meter when you try to wash your windscreen
