For that, you need to have a diagnostic tool that is two-way and able to turn on and off each of the individual solenoids inside the module.
And since it’s a BMW, there is probably a lengthy procedure to accomplish this. You will probably never get all of the old fluid out if you don’t go through this procedure which may result in there still being moisture in the system when you go to test for it.

I agree but after 17 years on my WRX, I have had no issues with just bleeding the corners to get the fluid out of the caliper. ABS still works, check it every winter in the snow.
