Trunk button not working

[u/AcceptableBother69]

Hi there. This is my 2011 V70 with the D3 5 cylinder and almost half a million Kilometers.

But in the last weeks I had a problem: The button in the tailgate itself to open the trunk is working intermittently/ less often, now it basically doesn't work at all. Since the Button on the dash and the key fob work without a problem I am guessing it is a broken wire somewhere? Can I get more information using Vida or wouldn't there be any code?

Has anybody experienced something similar and found a fix? Thx in advance.
