E70 Tailagte

[Jjrich]

Hi all, have an issue with my tailgate, will simply not open on the button ir the handle, once released manually from inside it will then close fine on the close button or the handle itself. Ajy ideas? I have checked all fuses but nothing, there is no aiund when you push the handle other than the small click you hear just depressing it. At a loss...🤨
