I recently raised my car (2007 E92xi) up using jacks and the stipulated jacking points for the front center and passenger front (side). I raised the car fairly high to install some carbon fiber bits and am now hearing a loud vibration sound in the cabin on idle. If I apply a small amount of throttle the sound goes away. I tried to take a video, but the sound was not audible in the video. It almost sounds like a buffering sound (as if you cracked a window in the car going down the highway). Does anyone have an idea of what this could be? I would appreicate any help someone may be able to offer.
