2009 c300 4matic 82k Buzzing noise over 30 mph

I have a buzzing noise when moving over 30 mph. Does not do it while revving in park. Its not the p/s pump , but dose sound a bit similar. I changed the serpentine belt and pulleys, did not stop.

Hello and welcome to the forum! Does the car perform differently? Any codes pop up?
