I had my top hatch fail on my '13, and I'm not sure what to replace. I've fairly certain that it's the actuator, as I can pull the cable and get it open. The cable is still attached at both ends. I can hear the noise when the button is pressed, but the hatch won't open. I have gotten the trim all removed, and ready for replacement after repair. I noticed that Atlantic British sells a "kit" that includes the actuator, latch, and dust protector. Is there a need to spend the extra money on the latch? I would assume that the latch is targeted toward the LR3, but I don't really know. What would make the latch itself fail? The local dealer quoted $900.00 for the repair as they said the only way to do it is to physically break the panel. I found the guide on AB, so whatever I get will come from them. Their video was for the 3, but the 4 is almost identical back there. The carpeted panel is much more difficult to get outta there, but it's doable.
