i cant find anything on how to remopve the old bumper. I've been told theres clips that i access through the trunk? i have a very elaborate show audio system that doesnt allow me to get there. is that how you do it? i also need to find a new valence for under the bumper which i have been unable to find (other than the dealer)

 

check out lltek or maybe an oem S4 one, and i think if you look under there it will be obvious on how it comes off
