Hi All,
First post so please be kind.

I have a rattle on my ED30, when at low RPM's it sounds like something loose, I have tracked it down ski hatch. If I undo and push the back plastic bit back in it stop's for a few days. Today I have just released it (hole through to boot) no more rattle

This took me ages to track down, sounds like a loose piece of trim in or under the car (especially when reversing)
Hope this helps.
