As I just posted in the Coupe section , I am a new owner of a 2004 XF. The hatch rattled on mine and CarMax agreed to fix it. Before I took it back to them I found the TSB here on the subject and fixed the problem in about 10 minutes.

I also noticed the door panel squeaks and rattles when I rest my leg against it. When I get the car back from CarMax (fixing seat heater and headlight fogging) I plan to work on that. Maybe some weather stripping around the areas that rub?
