Just a heads up for everyone, my Discovery 2 boot handle had started to play up, when you unlocked the vehicle with the fob and opened the boot all was fine but when it had been shut and i tried opening it again it was locked, after a lot off head scratching i found the problem was the edge off the parcel shelf would push the boot door pin down and lock it, so after a bit of brute force and straightening the parcel shelf edge the boot handle worked as it should.
