My 2009 E90 has a developed a strange short rattle sound that only happens with engine revving pass around 3500 rpm. I know it only happens when the car is moving, since I cannot just reproduce it when car is in parked position. It comes to me that it is coming from somewhere around center console/iDrive knob. Has anyone heard the similar rattle? I want to hear the melodic engine sound, but I don't want to hear this rattle as I go thru the gears!
Hopefully my dealer can fix it...
