Update:
My adaptive LED headlights do work
Thank you, it was simply because I misunderstood the option within the i-drive menu.
I'm pretty impressed with the technology, it's interesting to see how the headlights try to light up as much of the road as possible without blinding the other drivers.
I would like to increase the sensitivity so they're activated earlier. I haven't figured out the parameters yet but it seems like they tend to be activated above a certain speed.
It would be interesting to know how variables that can be changed via coding.
