i recently upgraded to hid low beams and led side markers,turn signals and drls. today was the first time i drove for more then 30 minutes at night since i upgraded my headlights.while driving i received a quick BOW for passenger low beam. the warning light went out but i could see the lamp was out. so when i pulled in my driveway. i turned the light switch from auto to off then back on again. the BOW came back on along with a check engine light. i went and grabbed my ross tech cable and my laptop.the code was NOX sensor seems like a common fault with our cars but car was running fine.i removed faulty hid that was melted and reset codes. rescanned and for now it is gone. is it possible that a melted hid could effect the NOX sensor. i wondering if these aftermarket kits could effect other systems.
