BCM PQ25 Max4 H80 0733 (7E0 937 090 Z4Y)
Used BCM Max 7E0 on allegro.pl costs about 400-600 PLN. There is a great risk that the BCM, which you order has a different designation PR Code than the Z4Y (eg. ZHH). It causes no property support of Full LED headlights. However new BCM costs more than 1500PLN, so you might want to take a chance 😉
I would like to thank Fernando (ciclo) for great help with this modification!
