My wipers have pretty much always been like this since i bought the car and I was wondering if it was just my car or an S3 design flaw. 1 - dont wipe properly at anything over 65mph 2 - sometimes start to judder (only fix I have found for this that sometimes works is rain x) 3 - dont alwasy clean the windscreen 4 - above 40ish mph tend to flick water on the screenas they return to rest. Now I currently have bosch aero wipers on normal wiper arms but even when I had normal wiper blades they did the same. Your comments would be appreciated. James.
