Headlight Control Module failure
I have an issue on the driver-side headlight, both the low beam and turn signal light are not functioning. I've checked and replaced both bulbs, but still no dice. Another thing I'm getting is a message about the headlight adaption or dynamic function isn't working. Currently, I'm thinking it's a failed control module for the headlight, has anyone else run into this problem, or able to tell me what that module all controls?

swap the control unit for sure and if the issue remains likely the ****y wires inside have lost the insulation and are touching causing errors. Then you have 2 options 1. Open and repair wires. Do so gently as moving them more will make the fall further apart. 2. Rewire the all wires with new wires. Will need wire and way de-pin each and re-pin. 3. All new OE used headlights that have been tested but know they will fail again.
