Many thanks for the advice - sorry it took so long to reply but I,ve been away & only managed to fix the car this afternoon. As you said, the lever in the wrong position was the problem. I think the reason it kept returning to a "central" position was that the flap used to open the boot had become stiff. Once I had opened the rear hatch using your advice I had to remove the internal trim. I eventually found that I had to manually return the opening link cable to a fully shut position for the central locking to unlock on the boot. Without doing this it would lock, then try to unlock but the lever would not stay far enough across. Hopefully a bit more WD40 around the opening handle sho ;Duld do the trick. Many thanks again.
