Morning folks.. Just had my rear wheel off yesterday to measure the thickness of my spacer, and noticed this! A few points... Obviously the arm is broken and not attached to the bottom bit... So would this not be an mot fail? And I can only assume that the wee box is working, ie power, because it doesn't show up on vagcom scan. This has been tied up like this since I bought the car, and it went through an mot for the sale... Can I buy just the arm bit and re-attach it? Perhaps from a breaker? Is there any way of knowing if the wee box is knackered too or if it's fine? I believe the front one is fine so perhaps is this why no fault code shows up? Cheers!
