Am planning on doing as complete a flush as possible and the online sources each seem to have their own pro's and cons :
---> Turkey bastering, filling up, engine start, turning wheel end-to-end, redo until clear fluid
Will be quite hard to recognize 'clear' from a black reservoir and guess will always keep old stuff in
---> Disconnecting oil line from rack cilinder, turning the wheel
I guess without the pump running you won't get all fluid from around pump area, with the stationary blades acting as a seal, although the rack is the lowest point of the system so maybe it does work if fluid can drain past the pump
---> Disconnecting return hose from reservoir, letting engine run with steering wheel straight, adding to reservoir until clear fluid exits hose
I guess this way you don't get all old fluid from PAS cilinder with steering wheel straight only (will remain old fluid left and right from the valve in the rack cilinder)
Probably the best is doing a combination of them, but that in itself has cons.
What's your way ?

BMW seems to specify topping up only, not a full drain. Getting it in is the easy part, getting it out is what's it about

Honestly, getting it out really isn't that critical. It's only low pressure hydraulic fluid - I bet the majority of cars get through their entire lifespan without ever having had it changed!

Is there not an accessible low pressure return pipe that exits the rack and goes into the reservoir tank? I would think the ideal would be disconnecting this pipe from the reservoir. Plug that port in the reservoir tank. Use that pipe for drainage. Have someone constantly pouring fresh fluid into the reservoir while somebody else turns the wheel from lock to lock. The job is done when fresh fluid comes out. Hey presto!
Im so good at doing things in my head. Shame that they dont always turn out the same way in reality...
