Long story short, I'm in the process of correcting/replacing some parts of my car from wear and tear, and im doing the left side felt and the front portion of the left side fender liner now. I am very confused as to what this #9 in the photo is. bmw calls it a "lower deflector" but it is not clear to me where it would even go, and i did not have one on the car when I removed #4 and the lower air damn corner felt. any help is appreciated, preferably with visual explanation lol.
