I was on my way home from work the other night and after a few minutes a crazy noise stated to emanate from the car. It was fairly loud inside and seemed to have started after shifting into second gear, it is an M6. It didn't stop until I got to a stop at a red light and had the clutch in. When the light greened and I let the clutch out to start going the noise immediately came back until I got to third gear and I haven't heard it since. Would anyone know where to start? Forgive the vertical video, easiest way to hold the phone and cruise.
