2014 E550 - 71-75mph engine high pitched humming
Been going on a while now...when you let off the throttle and decelerate/coast from 75mph-about 71mph...a high pitched humming occurs. Anyone notice this?
Definitely coming from engine bay.
Thanks,
JB

I do hear the same pitching noise barely notice it but it there only when i hit 69 mph to 73 mph
dealer test it said it so hard to trouble shoot exactly at that speed i just left it at that
I am ok with it but i hear what you guys are talking about

High pitched sounds are going to be very subjective to each driver based on the way your ears and ear drums are built.... There was a notorious high pitch whine in the g37 and for 5 years I never heard it and others on the forums were taking their cars back and forth to and from the dealership to get it fixed to no avail....

I thought the high pitch sound may come from Mirror housing design, so folded both side and drove on the highway around 70 mph last nigh; could still hear that high pitch sound
