Awesome. Ordered the part and now all sorted. Feel so much better and now I don't annoy the neighbours by setting the alarm off when I'm slow in the morning.
Also decided to fit aero wiper blades up front. Rear to follow soon.
Thanks all for your help.

While swapping the blades I noticed the little circular holes in the black windscreen border. Anybody know what they are for?
Cheers
