I drive a S2000 MY 2000 in the Netherlands. At very low speeds, only till about 20 miles I hear a buzzing, zooming sound. It's not loud but you can clearly hear it.
It does not matter what gear (1,2,3) or if I use the clutch.
Is this normal or could there be a problem with the diff or a gearbox-bearing?
Most of the times I drive faster than 20 miles though..................

Thanks.

 

If it only does it under decel, and the noise stops when you push the clutch in, it's the normal clutch buzz, as decribed in TSB 00-054.

 

Thanks, my clutch was already modified because of the deceleration problem.
This particular noise is always there (0- 20 miles/hr), accelerating or decelerating, clutch pushed in or not.
