He's saying that even when you activate the ABS in action like that, its not like fluid flows freely out of the ABS circuit and into the remaining parts of the system, it moves very little in reality, its just creating brake pressure.

I guess you could go do 20 ABS stops after a flush to try to get some of it to move through, but I am not sure that would even do it.

Agreed, the proper way is to cycle the ABS unit. Did I do it? No, I went to my buddy's garage with a lift and did it manually with NO ABS cycling. I'm fine with that.
Maybe one day when the X5 is in the dealer for something else and its due for a brake flush I'll have them do it by the book.
