Hello there! I'm Eurocar ! I will try to assist you as much as I can. Quality research = Quality answer!!
the problem with DRL with xenons is that the xenons is on all the time so to turn them off you do not have DRL anymore
there is a way to turn off the drl and the lights will come on when the headlamp switch is turned on but a VAG COM is needed to recode the system
the led's needs to be hardwired separately with a switch
technically it is illegal to turn off the drl's by the dealer!!
if you really want the led's major wiring and creativity is needed!!
want to give you the scoop!!!
i do know that. it can be mounted behind the grille but anything outside can be gauty!!!
it all depends you have to tag in the fog light for drl if you decide to change but fogs and leds at the same time may draw too much attention especially if all lights on !!
illegal to have fogs , high beams, and the led drl on the same time
max lights is 4
the bulbs are easy to replace . just look for the bulbs that fit the fog lights and sensor safe that will not trip the bulb out light
then code the module for the fog light as the drl
