My side marker is on after coding and the adaptive headlights are operating exactly as expected. As mentioned, I had Almaretto code my 2018 540. The performance on both my vehicles (M550 and X5) is exactly like my 540 and the videos that demonstrate how it should work. You can visibly watch the tunneling. So, not at all sure about what the side marker indicates. Perhaps that’s just an indicator for the factory to know that the disabling coding is enabled?
