Hi guys.

You got to help me, it´s driving me crazy.

I have a high frequency sound when i´m driving at cruise speed. It´s only appears when i´m driving at about 20% throttle, and disappears at greater throttle. It´s not there when the engine is at idle.

I had the crankcase vent valve replaced, but sadly the noise is still there, and driving me crazy!!

I have a E46 330i touring, 12/2004.
