Hi, even though someone helped me with the programming, I still had to take it to a workshop to perform the basic configuration of the LED matrix.
This can only be done with the tester.
After that, the matrix and data bus errors were gone.
Test drive in the dark.
Matrix is working

.
Thank you again

.
Is it possible to unlock the matrix function through coding on headlights that are labeled as "IQ Light" and referred to as "LED Plus" headlights?
