Hi. I recently drove over some biggish speed bumps and the car seemed to have developed a boot rattle. I checked the boot and it seems to be loose. Its locked and wont open but it moves around a couple of mm's so im assuming something has come loose. I also noticed the metal hook thats on the top of the bumper that looks the boot lid down, that moves up and down pretty easy. could that be the problem or are they meant to move to aid opening the boot? Thanks
