The proper way to bleed your abs hydro unit is to hook it up to a bmw computer if you have access to one or the software and cycle the abs pumps that way. If not take it some place like a grassy field where you can let the front lock up and the rear still rotate to mimic an abs scenario. I also did it once when I had my 135 where I put the car on jack stands (all four wheels up) and put it in gear and just let the abs cycle that way which worked for me. If none of those above methods seem to fix your issue. Your hydro unit may need to be replaced
