I have an 07 M5 and when I bought the car I noticed the driver side headlight and halo's were rather dim. I put new led bulbs in the halo's and noticed the original halo bulb bowls were burnt. I could not figure out why this happened, just figured it was crappy bowls. Then I received a parking lamp malfunction in I drive. I pulled the headlight again, and to my horror, I noticed all of the wiring inside of the headlight was extremely brittle and exposed (possibly from years of condensation). Some of the wire insulation literally crumbled to the touch. Even the fiberoptic cables for the halo's were completely exposed. I would check that. I literally took liquid electrical tape to everything and problem solved, headlight is back to original output and no more errors. If your adjusters are fine check the wiring as well.
