So I bought a car a month ago and my wiper blades are juddering, at first only on downstroke, since I putting them on fastest speed (where they don't judder ironically) they now judder on both up/down on all speeds except fastest.
Car is a 2017 Audi S3 3 door 8V model.
It seems to have been detailed in the past, it collects wax water droplets and the bodywork looks good when this occurs (beading). But it seems someone waxed the windscreen with some wax that is IMPOSSIBLE to come off.
I have tried the following
- new wiper blades, from Audi, twice.
- autoglym glass cleaner + polish
- T-cut
- jet wash
- vinegar and newspaper, 3x, over a period of 3 weeks
None of these has managed to get whatever is on the windscreen to come off.
It is so bad that if it rains I can't use the car. Not only because of the juddering but because whatever is on the screen collects all the rain drops and then you can't see out of the screen.
At 70mph all the rain runs off the top of the screen like RainX but I've never encountered RainX that behaves like this or doesn't come off with vinegar applied.
I don't really want to have to take it to a detailer who will charge me an arm and a leg to remove it? And a new screen I think is out of the picture as it has auto wipers etc.
It has audi warranty but I'm not sure if this kind of thing is a warranty issue?
Any ideas please? I don't trust myself with a machine polisher / wire wall pad etc.
