Sorry took so long to reply - waxed the car!! Blame me if it rains later....
Well mine does work, when the boot is open and the engine started the boot lights up on the diagram.
As for removing this panel (with the fogs, hazards on), I am not sure. It is easy to remove the heater panel above it - pull the knobs off, remove 4 screws (2 hidden under the knobs) and pull it off. You can then get to the top of that panel. You may need to remove the panel next to the air bag on the passenger side.
If your unlucky, you may need to remove the whole dash surround. I did this yesterday for half the car trying to cure the rattles - its not that bad - just screws.
There is definately no button on the boot or body frame of the car. I wreckon its in the boot associated with the lock. Try removing the panel covering the lock on the boot, and see what you find! The parts CD is useless..searched it for ages.
Websites are like ********s, everyone has one, and im wary of any bloke trying to direct people into their's
