Where abouts was the pic taken from? From outside, with the boot opened, or is it an internal pic? This the boot operational mechanism in my 2014 E class 220 W212. Its directly under the rear window. You can see it operating by raising and lowering the boot manually. And the 2nd pic is what I think is similar to yours ( except it does not have what look's like a compartment in it, or a plastic cover on the horizontal section ) I took this pic from outside, with the boot raised.
