My "C" regn Scirocco with a relatively new MOT when I bought it a few months ago, was making strange noises from the rear.
Eventually traced to this culprit and it was the same on the other side!
May be worth checking your car if they've not been looked at for many years as obviously mine hadn't . Rather surprised it passed the MOT to be honest when you see the state of the upper cups for the springs to "sit in".
Now sorted with the help of Shane , many thanks mate!!!
