I've only owned my Leon FR for 3 weeks now and since then it's always had this annoying rattle which sounds like it's coming from the boot area somewhere. You can only hear it when driving along bumpy rounds. Best way to describe it is like a bag nails clunking around in the back. My first thought was the jack and spare wheel, but checked that and it's all nicely seated in the cut out foam stuff so don't think it's that. Anyone got any ideas what it might be?
