The F10 535D (2012) has a loss of power once the battery is removed.

My educated judgement is that either a fuse has blown or one of the connectors on the battery distribution board has been detached.

To conclude this discussion.

Obtained entry via the back seats. I removed the base and detached the back rests, allowing me unrestricted access to the trunk.

Activated the emergency cord, resulting in the opening of the boot.

I briefly disconnected the negative terminal from the battery and then reconnected it, resulting in the complete restoration of the whole car's functionality. 🎉

The internal computer likely failed to reset properly when I first removed it.


I would want to express my gratitude to all those that assisted me. I really valued all the advice provided.

Thank you.

I am pleased that you have resolved the issue.
The issue with the boot opening is quite frustrating.
Due to the wind, one of my vehicle doors closed unexpectedly in the past. As a precaution, I now secure the door with a screwdriver until I am completely satisfied with the car or any other task I am engaged in.
