OK...I give up...in my 2003 ML 320, after driving, I remove the key. I still hear some very low noise fan or something like that when I sit in the drivers seat with the key removed. I don't know how long it lasts...at least 3 minutes, but when I return to the car it's gone. Once, while sitting for about 2 minutes, I swear I heard a noise like a vent closing. Am I nuts?!?!?!
if its a buzzing sound thats normal, I still do not know what it is but I do know it is normal, you can also let the car sit for hours, get in your ML turn the key to slot 2 (not the engine on just electric) and it will buzz again for another 3 minutes
would be nice if someone knew what the function of this was
