The boot. lock does not operate at times so a bit unsafe to use the boot (eg).just returned from a long W/E away, storing my gear on the rear seats and trying the boot lock (whilst away) by pressing the 0 in 607 after unlocking the doors manually (key only works manually) and after several attempts failed to open the boot. On returning home the boot opened when the 0 was pressed, but only the one time. Can anyone shed any light on this problem?
