I have a MK5 Golf Gt TDI 140bhp. The front washers have stopped working but still work ot the rear. Also the wipers stop working when the car stops moving but work ok otherwise. The bonnet open light on the dash isn't coming on so I had a suspision it was the switch at the at the bonnet catch thus stopping the wipers and washer at the front but I have crossed it out and the light still didn't come on. I have also had my mate put the computer (not proper vw computer) on the diagnostics but nothing showed. Can you help.
