I've got almost everything I need to fit proper Audi xenon headligfhts to my car. I'm only short of one ballast which I think I have found. I've found out that my car my not let me programme it to tell it that xenons are there and I may need a new control module to do so. Does anyone know how I might be able to check without havuing to plug the car in and see? I'm pretty sure that knowing my luck I'll need the new module!
