Maybe, not sure how accurate they may be. What's the powertrain package?

It's a 1,4L Petrol 90HP

Thanks! So I guess the "Door Warning Switch" could be rules out since the car is blinking when locking it twice? My fear is that something is keeping the BCM awake. Are there any good ways of figuring out what that might be without having diagnostics tool? I have a OBD2, but that won't show these sort of things as far as I have seen.

Does the luggage lamp go out? Is there a power outlet in the rear?

As far as I have seen the luggage lamp goes out and I have not found any power outlet in the rear.

Does anyone know what the current draw should be before the BCM goes to sleep and how long it should take? My draw seems to be constant around 300mA.. So I am starting to suspect that something is keeping it alive. I do have a weird knocking sound when running the window of the driver side up/down. Would there be a switch of some sort there that could prevent the car from entering sleep, thinking the window is open?

EDIT: Fixed knocking sound at least. Some black rubber thing had fallen out of its slot, touching when the window went up and down.

My wife’s has had both window mechanisms replaced under warranty, the drivers makes a knock again now it’s out of warranty.

Was just some part that had fallen out of its slot with me. Three black plugs that barely had any hold to them. Pushed it back in and hot glued it in place to prevent it from falling out again.

Still not any closer to finding out the current draw though.

Try taking the parcel shelf out lock it and see

Light went out, so that doesn't seem to be the problem

Do you have rec function on your SiriusXM radio in your car? If your answer is yes then it could be that your radio is recording those rec channels 24/7 which will drain your battery. This was my issue and Hyundai bought the car back because they couldn’t fix it.

Don't think I have that sort of radio in this car. It looks the same as on the image below. There is a fuse called "Audio" which I have measured and tested, that one is completely fine, so I think I can rule out the sound system?

Update:

Seems like I might have found the problem now. I went to a local shop and they read out live values from the car, and that showed that the switch for the glove box compartment was toggling on/off all the time, which would keep the BCM alive. Disconnected the switch and measured the current, dropped to stable 12mA and was peaking ~20mA when the alarm led was blinking. I have parked the car for the weekend, hopefully it will start on Monday/Tuesday. I will replace the battery since it has taken a bit damage from the discharges, but thought I might test with the current one first.
