I don't know if this is a problem or not. My 02 Boxster S is running great. Just passed it's annual mot with no faults found. However there is an annoying noise coming from behind drivers side (right) when I go over bumps or potholes in the road. I have to add that the roads here in the UK are at an all time low for pot holes. It's hard to describe, sounds like something is thumping about in the trunk, like a loose floorboard. I lifted up the carpet in the trunk and underneath there is a sheet of hard foam which is jigsawed together to form a hard surface under the carpet. If I tap this it's kind of loose and I wondered if this was the source.
I know from experience that a liitle vibration can be amplified by the body of the car. We have a VW Golf that also had a really annoying droning sound that appeared when the engine was labouring. This turned out to be two screws that hadn't been tightened around a filter casing near the radiator. Once tightened up the noise was gone.
There no continual noise, just over bumps and it's not there all the time. I also can't hear it when the soft top is down.

Anyone got any ideas?
