The auto-dimming headlight feature is not working on my 2023 x1. The symbol is illuminated on the screen, but the lights are not switching to bright. It is not an intermittent problem, the system is not working at all. Is there another setting I am missing or is this a software/control module failure?

are you referring to the auto high beam assist feature? that feature can be turned on/off in the settings menu. If turned on, it will auto activate high beam lights at night. If will turn the high beams off when it detects an oncoming car or when you're following another car.

In addition to what’s been mentioned above the auto hi beams, here are certain conditions that have to be met before the auto hi beams activate. It takes into account things like speed, traffic conditions & sunlight.

Speed?

Yes speed. If you are driving slowly , like in a residential area it might not switch to hi beams.
My 2019 RDX, which has the h h e feature, also works that way as well.

If I recall correctly, mine only come on above about 30mph.

have you ever been able to adjust the sensitivity of the auto high beam assistant? then owner's manual says to push the light stalk forward for 10 or 20(?) seconds to switch to more sensitive. however, I have never been able to do that. I wonder if that's a country-specific setting? I tried it on a couple of X1 loaners as well and also couldn't make it work.

I’m in Long Island in New York. I’ve not changed the sensitivity setting on be X1. It’s at the factory setting. They have come on many times like when driving on to a dark entrance or exit ramp of a expressway/thruway. As well as dark roads when I’m the only vehicle around. I’ve seen them turn off & back on when a vehicle was coming towards me.

I do recall the manual stating what you mentioned. And I remember setting my 19 Acura RDX’s sensitivity +1 over standard when I got it 6 years ago.

I'm going to have to check this out--they definitely come on when I'm in my neighborhood, but I may be driving 32-35 mph at the time. It's hard to test in "residential" areas near me, because most have street lighting which may throw off triggering the auto hi beam.

I have read the manual wrong. Read it again tonight and got it working. Although now I'm confused.

I pushed the light stalk forward for 10 seconds as directed. A pop-up message said "reduced sensitivity" or something like that. Does that mean the auto high beam will not turn off as much?

Also, I assume that when the engine is turned off and restarted again, this setting goes back to the factory default at normal sensitivity? (but can't confirm that either way) Whoever wrote BMW's owner's manual deserve to share a cubicle writing manuals with Andy Richter at Pickering Industries.

It's definitely not 30 mph, because mine came on last nite at 22 mph.

I’ll have a look next time I drive in the dark. But with the clocks having just changed, the lighter mornings might mean that’s not for a week or two.

I tested this morning on my way to work at the end of DST here in the US. Hi-beams kicked on and no one was behind me, and 2-3 times I slowed down and they shut off each time at 20mph.
