I've been getting the VAG stuff, £3.40 from my local stealers. Or free if you happen to know a VW mechanic

(but cant rely on this always, would be taking the p*ss a little)
It depends on weather you have headlamp washers.
I do. They pop out of the front bumper on the first spray of fluid. The manual says you get a bigger washer fluid tank if you have these fitted. To the tune of 5 Litres if my memory serves me correct!

The warning (if fitted, because it is only fitted with the optional 'Winter Pack'
)
Really? I'm pretty sure I dont have the "winter" pack? But I do have the highline comp - could that be it maybe?
On a more comical note, I must of jinxed myself with the post - it ran out the day after on the way to work. Serves me right I suppose for moaning!
