Adding to the Repair category in this thread, I replaced my lift gate actuator yesterday. Paying homage to the Land Rover Gods that I was able to open the gate one last time to do the fix. I didn’t have to struggle with panel removal from the inside of the cargo area.
The rubbery button above the license plate didn’t get enough juice to the actuator to fully open, it would just click. Just as I was prepared to climb back there and start digging around, I tried one more attempt with the fob. It had not worked in previous attempts. This time I heard a click and when I pushed on the rubbery hatch switch, the damn thing opened. Could not believe my luck. My advice— if you even have the slightest suspicion that your actuator is fading, get back there and replace it!
I bought the kit from AB but only used the new actuator and the water barrier. I hope to return the latch. I also removed the black plastic cover from the current actuator version. In the event I ever do need to get back there via the trim removal process, that cover would make thing difficult. Finally, I applied the zip tie hack to the point where the cable attaches to the actuator. This probably wasn’t necessary given the improvement to the connection point in the revised actuator, but it was easy enough to do and cheap insurance.
