Boxster 981 - rattling doing my head in

[contiva]

Hi, wondering if someone can help me. I have a 981 boxter that has something rolling around behind the bulkhead behind the driver seat.

Cornering or accelerating or decelerating and you can hear something rolling around.... initiall I thought a stone or something had been sucked into the air intact or something.

I cant get into see what it is but just about to take it back to the dealer to have a look - its just over a year old....

Any ideas?

Hi, positive its not the seatbelt.

Its a rolling noise coming from behind the drivers seat.
