A rattle mainly at low speeds over bumpy roads has been driving me nuts, it's not consistant enough to convince me it's suspension top mounts. Given the car has only covered 11,000 miles I'd be fuming if it was to be honest. The sound was almost like the rear valance being loose but it isn't.
I had a good ferret about in the cubby that holds the warning triangle, medkit, towing eye, locking wheel bolt key and the single screwdriver (What a toolkit we get these days)
I have also pulled out the entire foam moulding and felt around to make sure nothing was rolling around in the space, it's empty.
I did notice the wheel bolt key sits inside the towing eye loop and is a sloppy fit so could have been the source of the rattle so for now the key is in the glovebox. Everything else has been refitted and I will test further next week to see if the rattle has gone.
Hope it is as if not it's going in for an inspection as I can only think suspension or maybe part of the exhaust knocking on the tunnel.
