The rattle is from two vents behind the rear seat. These open to release the pressurized air when the door closes. They can be seen from inside the boot/trunk in the upper half of the panel behind the rear seat. Originally they would have had a piece of foam to dampen the noise but that will almost certainly have crumbled and disappeared. Hope this helps

What is the disconcerting rattle that manifests itself when I shut a door on the series II xj6? It emanates from the fuel tank area. I noticed this sound on other xj's, but it wasn't a problem on my series III. Am I about to drop a tank?
