FIXED!! Xenon LED headlights won't self level
...and the low beam is way too low! There is movement when I turn on the car, but it seems as if it's only a part-cycle movement of what the headlights normally do.
What do you think, is it the contraption/sensor thing on the suspension arms or am I looking at further (and more expensive) trouble. How do I go about diagnosting this? Disconnect the sensor front and rear in turn and see if it adjust to a standard height? Last edited by Estoril Blue 116d; 09-16-2018 at 06:52 AM.. Reason: Fixed the problem... |

Can it simply feel shy? (Did you make it do anything wrong? Do neighbourhood cars know?)
I guess the "heavy load" mode may be the default (conservative!) one and disconnecting sensors (that might have failed already) won't necessarily help. Another obvious way to test is raising the car's "butt" (just don't let other cars see that! ). Address a service. |

I would guess that there are fault codes available if you connect the car to a computer. And as I understand it, you have either LED or Xenon, not both?

I will get the car on some ramps and see if the sensorarms move freely or if they're all seized up? |

Thx mate, yeah I will have the car diagnosed on monday. I'll post here if there's any fault codes regarding headlights.

Another possible failure might be in the headlights themselves but it looks unlikely as they do move you say: "part-cycle" movement might be all right (limited by the sensors data) while the high beam (you didn't mention) should be still appropriately higher than the low (while not as high as in "no load" position, obviously). This is called Xenon headlights. They also have "regular" turn indicator lights you did not mention. (Completely?) LED ones come on LCI. (It's ovekvam who's had both. On different cars though. ) |

The headlights themselves seems ok. I did some night time driving tonite and the light output is strong, the full beam is really powerful and totally white but as you mentioned the light pattern is way off in hi beam mode. It's also too low (like the low beam) and kind of all over the place. Yeah I have the LED DRL / Xenon low/High beam headlights... and yes regular turn signals. |

I fixed it. The rear sensor was not attached any longer. The rivet holding it had sheered off. Also the arms weren't moving freely.
I will post pictures etc. on Instagram @estorilbluebmw Thanks for your input guys!! |
