2017 A3 Premium Quattro

Recently, the passenger side LED DRL stopped working and it didn't stop all at once. For about two days the light was completely out, so I decided to turn off the auto DRL feature in the MMI screen. On about the third day, driving at night, the LED suddenly came on and then off, then flickered randomly throughout the drive. The flickering only occurred that evening and has remained off for the past month or so. I looked under the hood and could not see anything that was loose. Attempted to wiggle the wires around to see if it was a connection issue but had no such luck.

Any thoughts or suggestions on what I should do next? Purchasing an entire light system just for the LED DRL seems a bit too much, so I am looking for affordable DIY solutions.
