Hi guys try to look after the main power cable pin 11 connector C1 the big one on the fdcm
It should be 12V permanent
If not just put a cable from one of the other red cables
I had the problem after the N23 recall meaning that permanent + was no more there it was a after contact +only giving 7V
It checking this pin is also the 1 step of the workshop repair guide but it's skipped form them as there is a bit voltage.
Since I made this I have no problems since months now
