BMW F3x electrical functions partly cut out or battery drains

BMW F3x lights, indicators and power windows all act up at the same time, what is the cause?
The cause can be the battery, even if it looks fine in a test. Replacing the battery has cleared the faults in the indicators, power windows and lights all at once. Also read the fault codes, because many codes can be just a result of the voltage dropping.
Why do the F34's tailgate, windows and rear lights stop working?
The cause can be the REM unit, which controls the car's rear electrical functions. A faulty unit is replaced, and a used replacement unit must be coded to the car, so the job belongs at a workshop.
