Audi A4 B5 8D Instrument cluster warning lights blinking/lit and no RPM
Hello
I have a Audi A4 B5 (8D?) from 1996 that is giving me an annoying problem.
From startup to turn off, it is blinking on the warning light for coolant and breaks, and warning is solid lit for fuel and oil.
The RPM gauge is also not working.
It also beeps 3 times right after startup.
The car is working OK, and can be driven without any problems.
I have checked all fuses, they are OK.
I have checked diagnostics, and it did not give me any faults.
I took out the instrument cluster, and checked the cables visually, they look OK.
I have looked at some schematics and all the +12 VDC and the GND seems OK.
I have tried a different instrument cluster, but the same fault.
I made a video of the problem, can be seen here:

Schematics I found was these:

Audi A4 B5 (1995-1998) Wiring Diagrams
Does anybody have an idea of what this could be, or where the problem is originating from?
I'm starting to think there is something with the ECU :\

Best regards
