Floor noise

[cobalt]

For months now I've noticed something which sounds like a stone or bolt running from one side of the car floor to the other when I go round corners. No sign of anything obvious under the seats or in the footwells - I've also filled the hollow floor crossbeam (which runs across the front of the seats) with expanding foam. Still no luck. My only other guess is that its coming from underneath the floor but as far as I know thats inaccessible because of the permanently attached undertray below the passenger compartment. Any ideas?
It's an S2 Elise by the way

Could be your handbrake cable scraping along the floor panel. This would give the effect of something rolling around the floor pan. Does the noise exist when you come to a stop (sudden) ? You can access the cable through the centre console from memory..

Only an idea but I have heard this before..

Thanks LL
Worth a look, although I can't say I've ever noticed it when coming to a sudden halt, just going round corners

Theres something in my passenger sill that slides around. I've given up trying to get it out and just live with it!

If it sounds more like a scraping I would say that will be it. Nothing to worry about in any case. It's always a nighmare trying to work out if there is a penny or something similar that has fallen through to the undertray etc.

The worst place is the slot near the handbrake sleeve. Its easy to drop something through there.

To be sure you could remove the undertray to have a look or reverse up some car ramps to see if said object slides forward..
