I have a 2005 330i that makes a intermittent rumbling noise while driving. It happens when I am driving at a steady speed and it stops when I accelerate or let of the gas. The noise varies at times. I took it to the dealer and they could not find anything wrong with it. I even for a 2-3 mile ride with a tech and nothing.
I think it may be the fuel pump but I am not sure
Any suggestions or help would be appreciated.
