Coding Light Sensor for Headlights

I have an 07 E90 335i with auto-leveling xenon headlights that automatically come on when it's dark outside if the headlight knob is in the auto position. I have noticed that the headlights come on too early, when it's barely dark outside.

Can the sensitivity of the sensor/headlight be adjusted with coding? I did a little searching and did not find too much info, but it looks like it might be possible. It also looked like the sensitivity can become an option on the cluster, that would be nice. I do not have iDrive, but do have FRM2.

Thanks!

Hello. It's possible in 2 ways. Or coding RLS permanetly with one sensity, or coding komby to get an option to set the light sensity from the sensor.
PM me if you need help.
Thanks

It can be coded if you have a k+dcan cable.

Sweet! I do have a K+DCAN cable and have done some coding already.

I coded the KOMBI to give the three options for auto headlight sensitivity. Now my question is, which settings are most and least sensitive? It's not intuitive to me and I couldn't find any information.

Figured out the settings with some testing... The 1 filled in box is least sensitive (headlights come on later/darker outside), and 3 filled in boxes is most sensitive (headlights come on sooner/lighter outside).
