S550 Drivetrain

I have a 2008 S550 4Matic. It has about 31K on it. There is a slight vibration and definate low pitched whine, moan? between 1300 and 1500 rpm. It does not seem to matter what gear I am in. I can control the noise with the throttle by going over or under those rpm's. Any ideas? Thanks Keith
