On the overrun, I'm getting an odd rattle as well. I think a good place to start would be that red panel you mentioned - on mine it is loose in the engine cover! I'm going to take it off this morning and put some double sided foam tape between the silver engine cover and that red trim panel.
Mine's a 1.9JTDm and it's the most untidy engine bay I've ever seen, so there could be a hundred different sources of a little rattle noise, but I thought I'd start with anything loose that rattles when hit with the hand.
