My S550 sedan had this - I took it in and it turned out to be a faulty ABC Pump.
Fixed it and no more noise.
I took it today and the shop foreman test drove it and indeed noticed the humming above 65 mph. And somehow it stops above 85 mph. Lets see what they say...
Sorry about my lack of knowledge. Im new to benz and this is my first mercedes

When I noticed on mine that it was making the humming noise only at the 1500-2000 RPM I thought it was the transmission. I really couldn't understand how it would be anything else.
They replaced the ABC Pump and the noise is gone. Above 85mph on mine - I heard no noise, or don't recall hearing.
It's definitely worth a shot though - the symptoms sound very similar.
any help will be much appreciated!

Went to dealer today and checked the car. The humming noise seems to be coming from glove box/engine firewall area. They have checked everything and still cant get to the root of the problem. Shop foreman said they will ping mercedes about the issue and see if anyone else have had any similar problems. Called the mercedes benz customer care and they will contact me soon about possible resolution.
Has anyone ever had their car replaced by mercedes under such circumstances? The car now has been in dealership for 8 days and still no ETA on the fix.

But you only hear the humming sound above 65 mph and stops above 80.
