Incorrect.

Same procedure as any other brake flush but with car running? Any tricks anyone can share?

I was told and read you need the special Porsche electronics tool with PSM to open all the valves.

no special tricks, and you don't need to have the car running. You're just flushing, the ammount of fluid trapped in the PSM components won't hurt anything. You don't have to replace every drop of old fluid. Whatever is left will mix with the new fluid during usage, and get flushed next time.

Great to hear. I was wanting to do this but read as I posted above. Thanks.
