You can manually move the positions, but there is a chance for damage BMW says, and then go to the dealership and have everything reset. I imagine they’ll charge you an hour of labor. Just keep in mind the car may not brake properly if it’s confused on the pistons position.

There's no software to retract the pistons as you can see. Still use a mechanical tool.
It's not really all that complex. Just a matter of following the instructions.
