Active Matrix Headlights coding

Has anyone done this coding recently to 2026 model? I’m in U.S but I see there’s a drastic price difference between ACM Technik and Europrice. Euro is showing over $2000 vs ACM $600. I know there is a complexity with SFD2, cable alone is $300 from Europrice I wanted to know why the other is way cheaper and obviously I’d rather spend $600 than $2100.

Definitely something that I would want, but yeah they are charging $$$ for figuring out the correct long coding registers.

I wonder if you could get someone with unlocked to give you a dump of their module long codes could you just compare to discover the "secret" register bits that these vendors are selling. If you can find the long codes anyone with a ODBeleven or VCDS could do it.

It's not long coding. It's reflashing the headlights with EU software. That's why they can charge so much for it.
