First we need to get into our trunk toolkit to get the tools we need (thank you Audi for supplying these!). Remove the spare tire to get to the kit.

Here are all the supplies: a new fog light unit, the Torx screwdriver piece, and the Phillips/Flathead screwdriver with universal grip. I thought I may need a larger Flathead for prying (didn't use).

And we begin: stick your fingers into the two holes of the fog light panel. Lightly pull until inner (left) side becomes loose. CAUTION: DO NOT FORCE PANEL OFF, YOU CAN BREAK CLIPS IF TOO ROUGH!

For me, the inner and middle clips came off easily. The outer clips were a pain. Slightly jiggle panel until it comes loose. Be careful not to pull too hard or twist so you don't break any clips.

You can see where the tough clip holes are. They are the square-ish holes on right top, and bottom. You can kind of see how the clips fit in and how to pull the right way without breaking anything.

There is a small clip holding the light and wiring together so we need to release the clip with our Flathead screwdriver. Then once it is released, the socket should slide right off.

Still not sure how this broke and there's no scratched paint around it. It's a mystery...

My bulb still functioned so I wanted to keep it for later use. Grab the back of the bulb and twist counter-clockwise.

Woohoo, now the light is in! BUT NOT SO FAST! We still need to adjust the fog light so (A) it points in the correct direction and (B) so we don't blind anyone with our new light.

Since my passenger side fog light was still adjusted at factory settings, I used that as my reference. See how on the left, my new light is slightly pointing lower so I needed to adjust it.

Take your Phillips screwdriver and stick into bottom left Phillips screw. Turn clockwise or counterclockwise depending on if your fog light needs to be adjusted up or down.

After adjusting, the fog lights now point in the same direction and we are almost done. (I forgot to mention I turned off my headlights while checking fog light adjustment).

We are now done adjusting so we can place the fog light panel back on. Easiest way is to get the outer-right clips in first, then the middle, and finally the inner-left clips.
