I have a 2000 328i that has a history of power steering fluid leaking over time. Over christmas break I changed all of the power steering hoses and reservoir, which fixed the issue. However last week while making a sharp left turn the power steering went out, and from what I can tell all of the fluid immediately left the system. When I got hime I refilled the system and when I went to turn the wheel, all of the fluid drained out. Does this sound like a busted hose, or something else entirely????
