hello everyone. I am new at this. I own a 1999 volkswagon cabrio. I was replaceing the head lamps(whole thing had to come out, cloudy covering) I had to remove the battery to do so. Now I don't have the codes to get my radio working without paying the butt down the street for it. I don't want to do that. That is why I work on my car myself. If anyone can help that would be great thank you.
