I do not have any problems with my lights. All lights are functional from a mere human's perspective. My car has developed this bad habit recently of displaying "Check Right Front Side Light!" fault any time I turn on the lights. This came up once or twice intermittently over the last couple years but recently happens every time. The following is my troubleshooting process I got nowhere with:

First I turned lights on and checked all front/side lights. All lights are functioning.

Next I removed both front/side assemblies (from bumper through wheel well. This was easier than I thought. 3 screws on each side out of the wheel liner and I could stick my hand it an press the clip in from the side light assy and the assy pops out of the bumper. I removed both bulbs and swapped sides. The problem did not follow the bulbs and the fault remained.

Next I removed the bulb from the left side and turned the ignition on as a sanity check on the faults. This yielded both Check Right Front Side Light AND Check Left Front Side Light. Ok good, I expected the Left side to come up now.

Then I hooked up the VCDS (VAG COM). I opened 09 Cent. Elect and saw the faults listed. I had the greatest of hopes that there was some intermittent connection problem and after accumulating enough times it would make the light come up and persist even if the light was functioning. This didn't pan out. I cleared all the faults, which made the light warning light and the warning disappear. Within 10 seconds or so, the fault reappeared! Every time I would clear the fault, it would show right back up even though there is no problem with the lights! The following is fault readout from VCDS:

I then went into the measuring blocks in hopes to find some sort of information on the side lights that could clue me in on a problem. The only thing I found was Group 41 where both front parking lights showed 99.6% and would cycle with the switch.

I'm stumped. Why does my car think there is a problem when there clearly is no problem? Help!

Problem Solved!

I replaced both left and right parking lamp bulbs from the parking lights in the bumper. Fault did not go away.

When I turned on my headlights without the ignition on, my xenons were off and I found the additional parking lights in the headlight housing itself. Sure enough, right side the little accent light was out. Opening up the headlight, you can see a big handle. At first, I thought this was some manual lever for the automatic leveling lights and didn't touch it. After looking at an online service manual, I saw that was actually just a handle to pull out the little blue peanut light that was burnt out.

While replacing the light, of course I accidentally dropped it into the engine bay. I couldn't believe it fell between the radiator and the radiator fan. Sigh. Lucky I grew up playing the game Operation. I took an old dipstick and wrapped the end in packaging tape and snaked it between the fan blades and somehow stuck the light and lifted it out.

Installed the light and fault never showed back up. This should have been a lot easier to solve but with as bright as the xenons are, I can barely look at the lights without squinting, nevermind see this little accent light. Learn from my mistake. The fault is the same for this accent light as it is for the true parking light on the bumper. If you get a "Check Right/Left Front Side Light" fault, check these lights as well.

Pictures explain it all...

Yes, I think my posts did a good job explaining what my error was, what light I discovered was out, and my solution to access and replace the out light bulb. All errors went away after bulb replacement. Take pictures or expound upon your issues if you want further specific help.
