If you have a scan tool with BMW specific functions there is an adaptive drive bleed setting but the bleed procedure is turning the wheel from lock to lock (all the way left, all the way right) about 20 times to bleed the system. Just do it until no more bubbles come up. I would have the front tires jacked up to do this as it’s generally less tiring.
You must use chf11s fluid in this system also.
