Thank You Ladies and Gentlemen.
The wipers are brand new, I discovered I had two brand new set, neither work.
They do have the severe bend in the wiper arm to create extra pressure.
The springs are obviously good.
Aerofoil may work at speed of course, not a bad idea. I have an old escort which I might nick it off
But it won’t help at low speed which sadly seems to be the norm on our congested roads.
Not had this issue on either of my 2 previous S1’s. All a bit odd
