Factory version depends when the car is made. So if made in July, the car will be pre-loaded BMS that can do timed charge but not charge when unlocked. On PDI, the dealer should update to the lastest version available on the workshops laptop, which at moment is the same early BMS as 'newer' BMSs has been pulled. If the dealer PDI the car in December then it probably got the range killer BMS. If the car is manufactured since late October then it might also have the killer range BMS, but likelihood of getting a car that new is slim as they are on a boat for 2months.
Depends on your dealership in terms of if they are proactive on contracting customers about updates post delivery. Covid does make things harder and a lot of dealers have limited capacity, so don't do proactive call-outs as they have enough service jobs to do. Also the updates are service advisory, so they dont have to call customers urgently unlike a recall notice action.
