Falcon tailgate hall sensor issue

I also have a Falcon, and I had a similar issue with my tailgate not opening properly. Did you check the wiring harness where it goes from the body to the tailgate? Those wires can get brittle and break over time, causing intermittent sensor faults.

Could you elaborate on the specific location of the wiring harness you are referring to? A more precise indication would be greatly appreciated.

It's located near the top of the tailgate opening, usually covered by a rubber boot. Just peel back the boot and inspect the wires carefully. If you're not comfortable doing it yourself, I'd recommend taking it to a workshop. That’s what I did in the end!

I assessed the area you indicated and saw no apparent damage. I'll take it to a qualified workshop as you recommended. The repair cost 95€. Thanks for your help.
