I've just got a 200tdi disco and have discovered the rear door (boot or tailgate I suppose it is) will only open by turning and holding the door key in the "unlock" position whilst working the door release handle at the same time. If I just unlock it and then try to open it, the little plastic lock button (the one that moves up and down and is visible through the window) just drops. Is this a common fault and if so is there an easy fix?
