When i drive and reach 25-27 mph, a noise starts to creep behind the instrument panel, sounds like something turning, and gets louder as soon as I reach about 60. It sounds so loud like a shrieking buzzer adn then it stops and then quiet....whew! then it dosen't come back but once in a while. Sometimes if I don't drive my Benz for a while...it starts up again???? I want to fix this before something major might break behind the instrument panel.
