Had a problem with my x type 08. The boot could not be opened.
The only solution was to remove the rear seat. To do this pull the bottom seat cushio, you can do this by pulling hard on front of the cushion about 300mm from the door on each side. The clips are quite difficult you may need o big screw driver to use as a leaver. Once the bottom cushion has been removed, the back cushions can be removed by removing the 6 tork bolts holding them to the floor. When this is done lift the small cushion as far as possible, the connecting pin will fall out. At this point you will be able to squeeze into the boot and release the securing bracket, enabling the back cushions to be removed, then you will be able to remove the remaining cushion.
Once in the boot remove the plastic lock cover by removing the two plastic pop screws at the top you my need to drill the heads off. Once you have exposed the lock mechanism you will see a hole in the lock with a leaver, use a screwdriver to move the leaver, this release the boot and it will open.
With our car we found the wiring in the rubber sleave between the body and the boot lid had broken. We replaced the wiring through the sleave putting joints through the boot lid and the body at the body end.
Took some time but with minimal cost
