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?

silly thought - are you sure it's not the passenger seatbelt?

The metal catch rattles against the door

Hi, positive its not the seatbelt.

Its a rolling noise coming from behind the drivers seat.

Twenty years ago I bought an MG Montego. One owner and a nice example. Soon discovered a worrying Klonk when I took a bend a bit sharpish. Right or left handers .... roll roll roll Clonk!... What's that?!

Later, dropped a pound coin down between the seats and groping around blindly underneath I grabbed ..... a Golf Ball.... Bonus....

Somehow the Golf Ball had entered a strengthened cross member running the full width of the car which supported both front seats. The channel provided a small rollway for the ball to move left or right and gather speed each time hitting the end side sills with a clonk.

No ball no clonk ..

By the way, I found my £1 coin plus three quids worth of other coins..

I had this n a z4 I used to own, was a 20p coin in the seat runner, once found... Noise gone!

On the 981 there are flaps which are part of the roof mechanism and which are right behind the driver and passengers ears - they have been known to rattle/knock.

Not a rolling sound, admittedly, but cabin rattles/noises are notoriously hard to pin point!
