Automatic trunk closer stopped working
My automatic trunk closer on my 2014 E550 stopped working. When I press the buttons to use the closer, the panel lights up but the motor is not engaging. Does anyone have any idea how to fix this? Is it a simple software reset? Thanks in advance for all the help.

Have you tried closing with the button on the door?

Lots of mixed terms being used here...
Anytime you press a button to start a function, it's not fully automatic... power assisted, yes, automatic, no. Now that I think of it, using the foot below the bumper (keyless go) is not automatic, since it requires your input to initiate it. But since the lid doesn't close telepathically, I suppose buttons and feet are as close to automatic as it gets.
The two lights are housed in a panel (more appropriately a "mount")
As Arrie suggests, please try the open/close button in the driver's door (push in), to see it that works. That will give a clue whether it's a trunk-lid button issue, or system-wide. If you also have keyless-go, does that method work? These are tests to narrow down the problem.

Thanks. When I do the open close with the door i can get the trunk to move up and down but not latch. Still no action if I press the buttons on the panel. I have not tried it via keyless go.

Mine's a '13 so I don't think the wave foot under bumper thing with keyless go came along until "14? your '16 has it with keyless go.

Happy new year! Hope all is well and warm in Chicago and Dallas, I have an off topic question; When you hit the E-S button on the console, what color is the "S" for sport mode on the dash? On my '12 the E and S are both gold, in the '13 the "E" is gold but the "S" is red. You guys?
Sorry for the thread hijack.
