Sound like a high frequency spring vibrating? I hear the same in my car. Every now and then its more like a vibration related thing though, not when i hit a bump, but if the road is rough or whatever will do it in certain gears/ speeds too. Cant figure it out either.

One time I had a small black screw in the rear cubby in the middle portion of my coupe that drove me crazy until I found the darn thing. Look for something similar inside the vent etc.

So, what kind of sound is it? Like an electric pump working? Or like something loose is vibrating?
In some cars driving over road imperfections under braking results in quick activation of ABS, which is immediately followed by a buzzing sound from ABS motor restoring the pressure in the system. |
