My 66 plated i10 Premium Auto has a problem with the tailgate unlocking.
When the remote key is used to unlock the car doors the tailgate remains locked.
However it will open with the remote tailgate option on the remote key fob.
Any ideas about where the fault is will be most welcome.
Thank you.

Two possible causes spring to mind. Either the tailgate release switch under the outside handle has failed, or the wiring between that switch and the body control module (behind the dash) is broken.

If I helped you fix it, why not...

Your support is greatly appreciated

I presume you are referring to the rubber covered switch which you press when trying to lift the tailgate.
That works when the tailgate only part of the key fob is pressed for a couple of seconds. Where exactly under the dash is the body control module?
Thanks for reply though.

Sorry, I don't know off the top of my head. And it doesn't really matter anyway if the tailgate release switch is working.

If the car is locked and you press the unlock button on the remote, does that unlock all the doors or only the driver's door? I'm not familiar with the Gen2 i10, but on some cars you need to press unlock button twice to unlock the passenger doors, and the tailgate.

Using the remote opens all the doors except for the tailgate.
The dealership suggests they will need two days as it could be any of the door locks causing the problem.
I am not to keen on all the door panels being removed.
I am sure the wiring diagrams should show how the system is powered.

I don't see how one of the door locks could stop the tailgate from unlocking. And if it was it should only take a few minutes to figure out which door it was using the dealer's diagnostic scan tool.

FWIW, what you describe sounds more like a software issue to me, rather than an electrical problem. It's as if the body control module has been programmed to only unlock the tailgate when the tailgate button on the remote has been pressed.

Thanks for reply. I will do a search for a local auto electrical and try and get some advice before committing to dealerships two days to see which door lock is the cause. Sounds like a interior door cards removal all around.
