Is that a B9 S4's trunk? Why did I think there was a temporary spare in there?

In my Lexus GS, similar looking sensor in about that location was the receiver for the keyless entry. Suspect that sensor picks up your remote trunk release and makes sure the key isn't in the trunk.

you dont have a back up camera? It comes standard on the S4 along with the front and rear parking sensors. You sure you have an S4 buddy? lol
