Hi all

i really needs help about "Headlight Range Control Defective" warning light and actually headlight range control doesn't work



i have vagcom so i've ran and tried everything but still not working....

01535 - Control Circuit for Right Headlight Range Adjusting Motor

so. let me tell you what happened before that showed up.

i have ordered OEM headlight ballast for my audi q7 3.0TDI and i've just replaced it without any problem.

i've plugged power into the right headlight and i forgot to plug the left headlight power and i turned on car.

and that error showed up so i've shut off the car and plugged right side headlight power.

when i turned car on, the headlight always been up and down but this time it didn't work with that fault code up

i have reset everything from vagcom and still not working.

I am thinking put the original ballast back and try it again

plzzz help me out !! it is so emergency

I have to go back to the army base in a day so i don't have lots of time to figure the problem out

thanks all for help

You need to click the link I posted, and follow the headlight adaptation (Aiming) procedure.

Its going to be that sort of procedure that will clear your error. That comes from this thread:
