Hi, I have a 2001 mark 2 with wiper blades curved up. the wipers work fine but I have the most annoying wiper judder ever. I have wasted so much time and money on new blades, cleaner etc. with no success. So I have just purchased from a breakers, two later mark 2 edition wiper arms with pin type flat blade clasps to see if that makes a difference. I have tried fitting them today with 28" blades but despite moving the arms on the linkage up and down I cannot get the wipers to stop clashing. I am taking the two 28s back to Halfords tomorrow. My thoughts are I need to try a 26 on the passenger side and a 28 on the drivers side. I think this will solve it. anything to stop this awful wiper chatter. I'll keep posting how I get on
