I have a 2002 745i that only has 75k on it. the steering has actually quit working once before to where I couldnt even steer the car. It has come back completely and other times gets sluggish if I try to turn the steering wheel too fast at slow speeds. What the hell is the deal with this thing? I think that the brake system and the power steering use the same hydraulic system and resevoir. Is the resevior also a filter and if I change it will it improve the power steering? The brakes work fine. Also I have a leak and believe it is from the steering. Can the computer be reset for the steering?
