Yes, it is worth fixing. If you don't, the headlights may blind oncoming drivers. It may be a simple Tech II setting. You'll get this if the angle sensors get disconnected. Of course, it may be something more serious, but I would have it fixed.
I had the same problem. Inspected headlights, wires, 2 sensors, took it for Tech II check, nothing...nobody knows why and mech said he needs my car for some time to find the issue. I finally got tired of pressing CLEAR button and took fuses out, and light never comes back on:cheesy: I hope when I'll have enough time or extra car or money I'll fix that problem, but so far I leveled them manually and doesn't seem like I'm blinding anybody.
