LCM II internal error, no check engine light

Had this old wreck for a couple of years, it works fine, starts up first time every time.
When I got the car the previous owner had drilled into the wood paneling, installed a switch to turn the high beams on as they must have been on all the time. I searched and found out how to change the responsible transistor in the LCM and the high beams are working normally again. 2 wires were cut by the lcm harness and I reconnected these.
I do not have any BMW programming software, NCS Expert or PASoft, I only have a Creator C110 reader.
The reader show no errors, except for the LCM where there is a lot but most everything works on the car.
When I got the car the errors in the cluster menu was:
1 BE C8 105
2 C7 81 000
3 D7 81 000
4 8C 84 000
5 92 84 000

A bit later they were:
1 BE C8 110
2 cd 88 014
3 d7 81 000
4 8c 84 000
5 92 84 000

I then looked at the fuel level senders and the are working again now.

Now its only one error:
BE 48 040

Some codes and their meaning:

1 Fuel consuming signal from engine control unit faulty

I had the cluster shipped away to pixel repair and its good now. Using test 1 in the cluster the VIN corresponds with the sticker and manufacturing date is accurate. I have no tamper dot.
Still, my airbag light has never been on (dont have any codes for it either), the check engine light has never been on along with a few other lights. I cant recall seeing the fasten seatbelt light either. The oil level sensor is working as I have been told by the cluster the oil level was low.
I admit I havent checked the cluster again since the pixel repair but I believe all lights are led? They shouldnt burn out and even if they did I would have some persisting codes from the Creator C110 then and I have none. The 110 doesnt read everything I know that.
Just hoping for maybe a miraculously simple solution, not sure what that can be, I didnt see any broken wires anywhere.
Had decided to just leave it but now I posted anyway...

The lower lights (5 in all) are incandescent, and have a funky base. Get 'em offline, or at a dealer. Rep[lace all, whilst your at it.

What is your overnight battery voltage?

Well, fiddled with the instrument, couldnt remember how to disassemble it so I had to find a youtube video, hope I didnt screw up anything but cluster 2 test is fully functional for the gauges so....
Airbag light comes on when ignition is on, goes away after a few seconds, the other lights come on when key is turned to second position but not the check engine light.
Anyway, couldnt find anything obviously wrong so we will see, not so important though, just would be nice to get a red engine light in case of total disaster....
The lights are led, forgot we talked about this in another thread so yeah, sorry, two threads about the same thing, I am getting old:

Those are the "trouble" lights. The LCD panels on my car are lit by bulbs.
