I had noticed that my cars wipers were starting to slow down just after I had washed my car a couple of times then they would go alright until the next wash, my car wasn't moved for about 8 weeks after I broke my arm and the wipers were solid so I sprayed them with WD40 which worked for a couple of weeks then they just gave up, so today I bit the bullet and went to Dundee Audi to order the linkage, to my surprise they had it in stock and only cost £62.05 (another surprise). I checked the picture guide which quattrojames gave a link to and replaced the linkage tonight in under 2 hours. It's good to know I can jump into my car and if it rain the wipers will keep working.
