That's my new fan washers ordered, my last car had them and they were much better and I never had to adjust or had any blockage problems as I have had with the standard ones on my S3. Looks a doddle to fix after viewing the video!
Here's the video as requested. I'ver never made a YouTube video so apologies for the lack of sophistication. Just sorting a problem out.....will repost (realised I posted the unedited video where I swore)
