Well I finally got around to replacing my broken fog light. Lucky for me the $123 light was paid for with my VW Dieselgate credit card. Everyone's help was appreciated when removing the painted valence. It took quite a bit of effort.
Something to note, the way the tabs are shaped, the valence is meant to pull out in a linear "forward, toward the front of the car" direction when removing. I loosened a few tabs but releasing the two hooked tabs (as indicated above in 3astan's post above) allows the whole piece to move directly forward and finally pop out. Conversely, when reinstalling, be sure to start lining up all the tabs before pushing in rearward to engage the final two hooked tabs. If you don't get all these tabs lined up before the hooked tabs, you will be unable to push them in correctly.
