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!
