Do you have a pressure bleeder? I don't use mine much and just bleed the system the old fashion way. Only issue is you can run low and pull air into the ABS which would require the pressure bleeder to get it to pass through.
If I was you I would hook a thin plastic hose to that particular bleeder and manually bleed it and see what comes out. Make sure not to run low on fluid tho! I poked a hole in the top of a glass jar and added a little fluid into it where the end of the hose goes as to not introduce any air between pumps. Brake fluid collects moisture which could be the cause of your caliper sticking. The water in the fluid is rusting the caliper piston housing.
Bleed that one first and then continue to do the rest. This might be one of the reasons BMW maintenance includes periodically bleeding the brakes etc,
