Question Details

I hear a humming noise from left side of engine compartment  for 1 to 5 minutes after I shut down my 2015 ML 400. Any insight?

Hi!

 

I suppose it has LED lights. They have cooling fans, which continue working several minutes after you turn off the car. 

Does it sound like that?

Good suggestion Boki. 

It could be the cooling fan as well. 

Have you opened the hood and tried to pinpoint the exact location?
