So I don't have my car with me right now, but your setup looks okay to me. What exactly makes it obvious that it is missing parts? Maybe I just don't see it, or maybe I just don't recall exactly what my 220D looks like. But as far as I can tell, that is okay. If you do a google image search, you can find a bunch of photos of that part of the car. And then compare to what you have in front of you. Good luck.
