The OEM bi xenon headlight have problems, and that's what you have. It is common to get a code indicating dipped low beam which results in the lights not working, burnout, flickering or other issues, The problem is determining the cause. My first guess is the igniter is bad, which isn't a cheap component. However, I need you to pull the bulb and check the socket for damage. Also, the igniter, which is known to burn up internally, should be checked.
If these items don't appear to be a concern and you're sure the bulbs are good, the next item is a bad headlight ballast. Again, it's not a cheap component. What I would suggest is this. If there is no obvious concerns with the igniter, bulbs, or bulb sockets, you should take it to a shop for inspection. The reason I recommend this is because both components are expensive and they can be really tricky to troubleshoot. The Ballast is well over a hundred dollars, and the last I checked, the igniter was over 200.
Let me know your thoughts.
