e87 trunk not unlocking from central locking

[Tommior]

Hi, this is my first post, and I am sorry if I have made mistakes on category or something else.

So, I have 2010 bmw 116, 2.0i.
I have owned the car for good 2 months now.
Otherwise the car was, and still is solid, BUT, it has this one little fault...
From outside I can only unlock the rear trunk from the bottom button, which I have to hold for few seconds. Then the trunk "pops" a little open. Shouldnt the trunk be unlocked from central locking?
Both my keys work the same.


It had this problem when I bought it. I thought it was just bad battery, which I already replaced. No effect on the problem.

Could this be fuse related? I know where to fuse box is behind the glove box, but it seems to be very hard to reach. Has anyone removed any plastic covers under the glove box? Or how do you guys change fuses?
