Anyone had a strange metallic dusty taste inside the car when driving? Doesn’t  taste like antifreeze which is normally sweet. Tdi vRS 67 reg

Windscreen washer fluid smell when you use the wipers?

^^^. That.

Don’t think it was washer fluid as it’s there when I’ve not used them. 

your not supposed to taste the antifreeze.
