From my point of view this is difficult. I would open the Pentosin reservoir, take the mesh screen out und get a suction cup? and try to remove as much of the fluid a possible. Than I would open all hydraulic line with easy access and drain same. Like the cooling loop in front of the radiator. You could also open just one line after draining the reservoir and idle the engine for a very short time like 20 seconds. The hydraulic pump will empty the system rapidly. This will be a mess. Then you shoul replenish and bleed the system by turning the steering wheels from left to right a couple of times (with the engine running). You may have to repeat that to get more of the ATF out of the system. BTW the blake system (fluid) does not have any connection to hydraulics. Just via the hydraulic servo actuator. Bleeding the brakes, especially with ABS and ASC+T is a different story.IMO this should be done with a pressure system via the brake fluid reservoir. By a knowledgable shop (dealer). Not necessary BMW but not a Volkswagen dealer either. Ekkehart
