Loud buzzing noise from front of vehicle
We have a 2020 GLE580 and just recently noticed a loud buzzing noise (not fan noise) from the front of the vehicle seeminginly when the ignition is in the "on" position, but the motor is off and in "eco mode".
Any ideas? I am suspecting the electric AC?
Here is a link to a YouTube vid for the sound: https://youtube.com/shorts/So6yCXojloM?feature=share

I'd guess it's the air suspension doing an adjustment.
Does it only last 5 - 10 seconds?

No, it will make the noise for as long as the engine is in the "on position". And I have heard the air adjustment before and this is not the same.
