Hello JEG23,

I have requested my dealer to adjust this value when my car goes in for service next week, as my lights keep coming on when the sun is up.

However, a quick question to you (and anyone else who has tried this) before I proceed with this: On cloudy days the lights comes on at a pretty good point I think, just when it starts to get dark enough that it is hard to see the instruments on the dashboard. Will there be a dramatic delay for the lights to turn on also under these circumstances, or is the change mainly in how the sensor works on sunny days?

I want the lights on when it is bright outside, but then again I also want them on when it starts to get dark outside, especially considering that it is nice to get the dashboard lights on to easier se the speedometer etc.

NicNoh,

For me, the change as described in the first posting works great. The lights are not on in bright days and they come on at the right moment when it becomes dark or it is very cloudy.

That said, all of this is a matter of personal preference. That is the beauty of coding. You can try “unempfindlich” and if that is not sensitive enough, you can then try “normal” and that may work better for you.

As for the dashboard lights, how they turn on is a complex process in this car. The dashboard lights (at least in the F10) change from bright white during day time to orange at night. This process can be adjusted by experimenting with the code I posted here:

In my case, I prefer the bright white dashboard all the time, so that is the setting I describe there (FF). Other hexadecimal values will allow the dashboard lights to change from white to orange at different environmental light levels.

JEG23,

Thanks a lot for your quick response. That settles it for me. I will ask them to change it to unempfindlish and ake it from there. I haven't gotten into coding, but my dealer is fairly happy to change this type of things.

NicNoh,

Our cars (at least in the US) come by default in the "sehr_empfindlich" (very sensitive) setting, which is terrible as far as I am concerned. Try unempfindlish and if that is not sensitive enough (I see you are in Sweden where there are probably pretty short days for good part of the year), try normal. At least for the south of the US, normal was still too sensitive for me.

You should learn to code

It is more fun to do it yourself.

JEG23,

As I understand it, the setting is the same here in Sweden also. As for headlight coming on in the evening or in overcast weather, I am generally fine with the sensitivity, but what really annoys me is when it comes on in bright sunlight, especially when the sun is standing low. But I will ask them to reset to unempfindlich and see how it works. My only concern is that the lights will not come on when it starts to get dark.

Does anyone else have experience with changing this setting? It would be fun to hear how others have adjusted this setting and which setting serves you best.

The "official" BMW way to change the light control sensitivity is to use K-Words FLCN and FLCS:



I have not tested them though, and the underlying FDL Changes may be the same JBBF codes JEG23 posted.

shawnsheridan,

OK. So if I want the dealer to adjust to a lower sensitivity, then FLCN is the setting I should request?

Yes, and they would add this to your VO and program the car.

shawnsheridan,

Thanks, I will call them this afternoon to discuss this as my wife will be leaving the car in the shop tomorrow morning.
