My headlight went out on my 04 Toureg. On the assembly it says xenon but the headlight is hid I believe. It has a small metal square attached to it. I ordered new lights off eBay but they won't work. The local vw shop couldn't give me an exact answer to the problem. They only do the first 30 minutes of diagnosis for free and had no bulbs on hand to try. Any helpful ideas would be appreciated. Also where to get cheap vw parts that work.
