    Retrofit xenon/led in a Caddy 2018

    Hello guys,

    We have retrofitted xenon headlights in a 2018 Volkswagen Caddy.
    We have a problem to activate the drl lights.
    The headlights highbeam and low beam work perfect (with shutter) the direction indicator works also fine.
    We checked the wiring diagrams from halogeen headlights to xenon headlights and it's all a 10 polig connection and all the positions are the same.
    So we think it's a coding problem.
    Could someone assist us please?

    you need to change byte 18, when you change it you might need to experiment before everything will work ok, but be warned once you change it you can't go back, since 00 is just a mask for a hidden value

    Are you sure the current BCM can support LED DRL via PWM?

    Yes im sure the bcm can do a pwm output to pin 10 and 4.
    I was affraid to bridge 10 and 4 because the voltage is switching from 10 to 4 and the opposite, thought i would destroy the bcm if i bridge them.
    You guys think i can set my bcm on byte 18 to a pwm signaal and then bridge 4 to 10 it will work??

    As I'm looking some more information about this myself, seems like any Caddy that has Xenon uses 086AA BCM. I'm Thinking You should also.

    VIN from this car shows that this car uses Xenon:
