Like which spring?

I think Carlos is talking about an internal spring that puts pressure on the rack to keep it meshed with the pinion gear.

so its that little green spring that makes the loud noise every time?

No, I was thinking it's a loose rack grinding along the pinion or something like that. Does it happen when the car is stopped, moving, or both? If it happens with the car still (and it isn't the pump or a bent pump bracket) I'd try to figure it out just from where the sound is coming from. Can you narrow it down?

it happens both when still and moving

I'd try putting it up on jacks - if the noise is still there when the front end is unloaded like that, check the rack carefully. If the noise goes away, check the pump or upper bearings on the struts. I'm betting on the pump. The BMW P/S system is famous for failures.

thanks dave but i doubt its the pump because before it use to make a small whine and when i topped off the resivor with fluid the noise went away but ill do this procedure this weekend and ill keep you posted dave thanks for the help

Is the noise more pronounced at low speed and then goes away as speed increases? Does it sound like it's coming from one side more than the other? Open the hood and stand outside the car with the engine running and have someone turn the wheel, put your hands on the strut towers and if you feel a popping or roughness in them it's the upper strut bearings.
