Its the gen 8 manual that i need, thank you for helping. The tailgate stopped working to the key fob when i noticed the boot carpet wet. About 5lts of water in spare wheel compartment. Sorted roof rails, now fully dry.
Boot raises when button pressed but wont lower on button
That didn't come out right, what I meant to say was how do you know the water ingress and the tailgate fault are related? I've had to look at the wiring diagram for my tailgate too and was going to suggest looking at the wiring for 7th gen tailgate as well as I doubt they're that different.
A link to 7th gen workshop manual is in in my signature.
If tailgate not working and nor is passenger window or left hand folding mirror, the fault is with the circuit board in the passenger door below the electric window switch. Mine just needed stripping and cleaning with contact cleaner. Doesn't sound like the fault in this case but may help someone.
