They are the same, FA is the German language acronym for VO.
The key point is that the FA/VO
on the car is used during a programming session, to determine what the coding values are set for the new i-step.
When a coder does the VO Coding it's the FA/VO that is loaded in esys that determines how the ECU will be configured. Good news is that if you never write the FA to the car then BMW will never notice any difference if looking. Bad news is that any programming session will wipe the modified FA changes e.g. if removal of 8TR is not written to the car, then auto lane change will stop working after an i-step upgrade.
