Update to previous post: I fixed my adaptive headlight error by moving the ballast.

Everyone with similar problems please check out post #35 in this thread:

Wow, I learned something new. I just assumed everything in the rear bulb / rear cover area was just connectors and wires, but the adaptive motor actually extends back to this portion. If you touch & wiggle the square block you can see your headlight assembly (the adaptive headlights) wiggle too. So if the ballast is touching the adaptive assembly, it'll throw this error code.

Luckily I caught this on the first night before the motor burned out. Hopefully the rest of you can resolve your error codes now too.
