huh, I use halfrauds screen wash for 1.5 years since i go the car and also tap water. No problems so far. The only thing I hate is that when I wash the screen the headlight washer thing suirts as well spraying the bonnet and wings in washer fluid. Wish I didn't get this now as it make a mess.
So annoying isnt it !
I don't know where it is, but somewhere there is a fuse list for the MK5. Just pull the fuse out for it and bobs your auntie, they wont work keeping your bonnet nice and clean
