I can report no problem at all with Motive bleeder. Fluid easily flowed all wheels; flushing quick 'n' easy.

Soooo, OP....

• You tried pumping the brake pedal, no pressure bleeder attached?
  
• And you tried a pressure bleeder up to 20 psi, still no-go?

I still believe there is an issue with the Schwaben‏ pump. When I got it to "work," there was still air in the line of fresh fluid going into the car. Also, I went straight for the front corners of the car rather than from the back first, which is out of proper order. I'm not sure if I got a proper bleed. The pedal feels good enough I suppose, but not as stiff as I would expect, especially with having stainless lines.

The pump says not to go past 15, so I think 18 was the max I had it to. I didn't want to try 20 for fear of having too much pressure in the system.

Having air in the line feeding the the reservoir is OK. That is the air from the tube before you pressurize and air from the reservoir being displaced by new fluid. I did the flush last night with the motiv bleeder and had no issues. I was sticking to 20-25 psi. Even still, it was a slow flow out of the bleeder. Fortunately, the new fluid was a different color than the old fluid so i could tell once the line had been flushed. In total I used about 1L of fluid.

Flow is always gonna be slow, since you are squeezing rather viscous liquid through a myriad of tiny hydraulic lines, so don't except to be a garden hose. It takes around 5 mins or so to fully flush out each corner after you crack open the bleed valve from my experience.

Does the gravity bleed method not work in a BMW??

Wtf is gravity bleed? It is not like you can hang the car up like a dead pig and bleed it dry. You need pressure one way or the other to push out the old fluid.

Lol.

Seems like a good way to get air trap in your system. Doubt this method will work well for any modern car with ABS.

If you don't want to use a bleeder. Just use the good old pump and bleed method...

That's the way I used to do it on my S2000. Break pedal was rock solid when done...
