any idea what might be the cause of this error triggers simultaneously?
is there any module that control all this stuff together that might be defective?
can it be a battery problem?
the errors come and go from start to start

No expert but how old is the battery, would be the first place to start and probably the cheapest

I was always getting Bosch dsc errors on the obd reader and recently ebrake voltage error.
Just replaced the battery, i need to go back and cancel these errors to see if battery has cured those problems.
I replaced with a Varta battery, about £130 ebay.
I registered with my obd reader.
Gives option for agm or std battery.
It asked for some numbers off battery, which i couldn't find, but looks like even BMW on the first battery didn't bother.
My old battery was Halfords Yuasa, with a 4 year guarantee, so one assumes these batteries good for 5 years. Mine was 6 years old.

Almost all those errors involve the DSC unit…
As others suggested status of the battery would be a good first move.
FWIW if there are no other errors showing on the code reader I thinks it more than a battery issue..but..try with a fully charged battery..

We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard..

Could be a poor electrical connection at the ABS pump connector. Try reseating it. Remove the plug and then put it back on. It's a simple first step.

IMHO good first step…FWIW battery looks pretty healthy if the diagnostics are to be believed..
