S80 V8 is dead but brake lights are on

V8

I came out to my car one morning and the brake lights where turned on and can’t be turned off but the car was dead. I unlocked the door with the key because the central locking didn’t work. Then I put the key in the ignition slot and tried to start but the car was dead. I tried to charge the battery but still the same problem today. I got help from a friend and read some codes. I’ll try to post a picture of the codes. Can anybody help me to understand what’s wrong with my car?
All of the instruments are black but inner roof light works. Park lights work when key in the ignition.

Sorry for my bad English, I’m from Norway and don’t write English very often.

The picture is too small to read - can you try again?
If it's the brake lights, maybe a bad pedal switch is draining the battery or water is shorting something in the boot?

Is this better?

Your English is fine 'VDN'. I don't know about the codes, but I agree with 'seanc' that this sounds like a bad brake-light switch causing the lights to remain on, thus draining the battery, with the results that you describe.

As others said, check the brake light switch. Read this:

Basically brake light is #1 priority message on CANBUS and if the switch is stuck it can flood the CAN network and prevent everything else from communicating. Unplug the brake light switch and see if it resolves, as per the article.
