I don't have a bentley manual but wondering what it recommends.
I did this in my e36 but now am thinking about changing my 330i's fluid. It makes a light noise when I turn my wheel at morning start. Thanks for giving me something to start with.
Thanks! I'm not sure if having the reservoir cap open while the engine running is a good idea because if it's anything like a honda ps system, the fluid in reservoir spins around like a tornado. (Think opening a blender while its making a smoothie).
But hey, I'd try anything to reduce the amount of air that's introduced in to the system.
(might not matter thought as any air gets pushed out with force,)
btw, my steering feels much better (softer) after the change, with absolutely no noise.
