dealers are deaf
They couldn't hear the noise.
It's definitely not the speakers but it does sound like 2 wires touching to make a buzzzzzz noise. It could be my seat, or maybe something to do with the back head rests? Where else should I look? Thanks.
Take it back and have them check it again. Insist that it makes the noise and possibly give permission to check it out overnight. Otherwise, have someone ride in the back seat and see if they can locate it. Just realize that if the technician drives the car for 3 hours and can not duplicate the noise, he gets paid zero....not a dime.
I had an 06 ML 500 with a buzzing noise from the rear cargo area a week ago.. I removed some panels and found a bent clip from the factory.. I replaced it and road tested the truck and honestly couldn't hear the noise. The client came back yesterday with the same noise. I went on a drive with him while I sat in the back of the truck and heard exactly where the noise was coming from. I pulled the panels and found that the ETR for the rear seat belt was rattling on the left side. Believe it or not, there is actually a DTB for this noise, but it only states that it is present on the right side ETR..
Good luck.
