BMW F30 LCI LED Headlight Vertical Aim Control Failure
Hey,
Wondering if anyone can help... I have a BMW F30 2013. I use to have Xenon lights but did a retrofit to 2016 LCI LED Headlights. They've been running fine for the last 1.5 years. Last week I had an error pop up on the dash "Headlight vertical aim control failure" I don't see any visible difference in the performance of the lights so just want to get rid of the problem on the dash. The only thing of note (which may be expected is when I switch the engine off the fault does not appear). When I start it again and the lights auto level the error appears. Does anyone suggest any actions before I take the car to get diagnosed? |

When you start the headlights, do the headlights go through the adjustment phase?
They should aim slightly down, then come back up.

Update on this. When I start the car the n/s headlight levels immediately but goes up and down very quickly. Shortly after the o/s headlight levels at what I'd describe normal pace.
Usually both headlights level in sync. It appears one does after the other now. |

I doubt there's anything wrong with any of the the control units (LHML, LHMR). Unfortunately, judging by your account it seems like there is indeed a malfunction with the actuator on the driver side headlight.

I'd bet it's probably pretty hard I also think that BMW only sells full units - no replacement parts for them.

That does indeed seem a potential part. That said, you need to do a bit of diagnosing before you go buying replacement parts.
