I am looking into this retrofit and looks like it is not too expensive from paper... Only expensive in time as wires run all over the car.
From what I found out you don't need all handles to be Comfort Access, so you can start with driver only.
Keys probably don't need programming as our cars already have convenience Access aka, start the car with the key in your pocket.
I also ran a TAL calculation against with edited VO for 322 and no missing hardware showed up in 322. for my car. Everything was black so I assume I don't need new BDC if that is ever the case.
Only thing I don't know why / what is the function of the tailgate lock button? I cannot find this button on wire diagrams either.
I currently have Number 2 installed, do I really need to change this one to number 4?

So IMO in order to get s322a working in your car you will need to do the following;
1. Complete installation of all parts required for s322a, this includes all new door handles, door wiring, new tailgate closing switch - part 61319275121. Your car is showing it does not have option s316a (automatic boot/trunk closing) and I am assuming that you have already retro- fitted this because you say you bought the trunk smart opening module as well as 3 antennas and wiring. So internal boot/trunk release switch in driver door also needed. New comfort access key fobs also needed.
2. I repeat that in order to use BMW comfort access ALL /100% of parts have to be installed not just boot/trunk smart opening and antenna.
3. When all s322a required parts have been fitted you need to use E-sys to VO code your car with options s322a. This coding will/should activate the BDC communication with the comfort access parts including trunk smart opening module and antennas.
4. I cannot see that you would need a new BDC although the part number you have quoted in first post “6825528” appears incorrect, I believe you meant 61356825520.
In summary, comfort access retrofit requires a lot of parts, you cannot do half or only certain parts of the install because in order for function to work your BDC needs to be coded (it is not plug and play). In order to code BDC all correct parts are needed. As an example the smart opening module will not be able to communicate with BDC unless the BDC is coded. Your BDC will not communicate with antennas unless it is coded to do. Whoever does coding for you (using E-sys) may also need to code (CAFD) the new module to ensure it is running same istep (software version) as the rest of your car.

1. I believe you don't need everything but you definitely need all antennas
2. Why? I think we can skip some corners, F45 2016 model for example only had front doorhandles installed. I don't think there is a check for door handles, there however is a check for antennas which will result in fault code if not installed.
I think also these two FDL values in BDC_Body can be used to controlled if Doorhandle is comforat access or not but not sure.
Anyway, might be interesting to be noted.
CAH_ENABLE_REAR
CAH_ENABLE_TAGE_PASSENGER
3. Yes, must, nothing to add.
4. I have came to the conclusion that BDC 6825528 is used in production of cars however cannot be bought as (spare)-part. Not all parts are listed in ETK / realoem.
Does anybody know which interior antennas are preinstalled?
I guess;
1x steering column, close sensor
1x center console front
1x center console back
So I think we only need to retrofit;
Sideskirt L (exterior)
Sideskirt R (exterior)
Rear Bumper (exterior)
Luggage compartment (interior)
I got a deal for 200 EUR on smart opener ECU + Sensors, 1 exterior antenna and 1 interior antenna and Left Hand doorhandle, so I took the plunge.
For the 5DP retrofit I need to run some wires to back of the car so I thought I could also run the wires from the rear bumper to front as well.
