Rattling Sound - but not undertray bolts

[BigNath]

Hello,

My car has a nasty metal on metal sound, like the undertray washer, but the undertray bolts are all well and truly tightened. The exhaust is also rattle free.

any thoughts/

Cheers,

BN

What engine speed does it happen at?
I had a loose nut under the passenger seat which was causing nasty buzzing at about 2700rpm.

Just about to post the same except it was one of my GFs earings, the noise bugged me for weeks until it found it's way out to somewhere I could see it.

Check the state of the exhaust system mounts and brackets. Could be something amiss in there.

My friends.

It seems to be the inside brake pad on the driver rear side. No knocking going over bumps when the brakes are on.

Thanks for the suggestions.
