    The one that I\'ve heard in person

    had a nasty metallic clatter that went away when he pushed the pedal down.

    the clutch in.

    Would the car make noise? Ask real questions

    Get real answers. The throwout bearing works when you push the clutch in. The cassic symptom of a bad throwout bearing is a horrendous squealing noise when you push the clutch in along with quite a bit of pedal vibration sometimes.

    My understanding of the BMW part is that it does spin all the time. However, even with some noise at idle, it WILL increase sharply with even just a light pedal pressure rising to a full crescendo as your foot nears the floor.

    If your car makes a noise, a better description would help...

    Everything in a car makes a "noise" or a sound if you will, when the noise becomes excessive is when we get concerned.

    Beemrmaxwell: Thanks for your help....but

    less attitude would be nicer.

    I just wanted to know what the symptoms of a bad throw out bearing are...that's it.

    Mine is bad.....

    As soon as clutch is pressed down at all, you hear a light noise that I could only describe as metal lightly rubbing on something..... Not sure what else to call it.

    I guess it depends on what\'s wrong, then...

    this one was installed backwards, and had a nasty metallic clatter that went away when the clutch pedal was pressed.

    Mine does exactly that

    and has for a long time (since I got the car, 32k miles ago). It is quiet when I engage the clutch, noisy beforehand.

    Input shaft bearing, typically noisy on 5sp.

    The noise in neutral with the clutch pedal out is input shaft bearing noise. This is apparently a known issue with the transmission, and is harmless ("they all do that"). Replacing the bearing is a Big Deal and only quiets the noise for a little while.
