Hi does anyone know where i can get one of the little clips that holds the cover in place, sorry don't even know the correct name for it. Any help appreciated. Thanks

The cover is just one piece of plastic - I don't think you can replace the clips on the cover, just the cover itself. I got mine from eBay when I have to replace them a few years ago. But once you have the part number from that listing (3T0955109 - left and 3T0955110 - right), then you can try Amazon or online motor factors or local motor factors etc.
