Red led on door?

The small led on top of the door card doesn't go off when the the door is unlocked but everything works, door locks/unlocks like it should, no alarms going off (not sure I have an alarm on it) etc.

Is it trying to tell me something?

Did you check all the doors? I have a problem where one of the rear doors doesn't always lock. The light on the door stays lit when this happens.

Yes, all doors and hatch. Didn't check the hood though. I checked for fault codes and there weren't any.
The led is not lit today... Strange.

Micro switch in the door latch is probably flaky. Do the interior lights stay on as well?

The interior lights was not on when the led was lit. It hasn't happened since, so I'll leave it until the next time. As far as I know everything worked like normal but the led was turned on. Not flashing but solid.
