Iv had a golf fitted with oem gti xenons, Iv since sold the car and removed the headlights. They are on eBay, and also have the kuftec plug and play cables. Once they fitted, jus need some one with vagcom to code the car to tell it has xenons. Pretty straight forward. Had a mk6 GTD and had the original led and xenons fitted with no warning lights. The oem kit is a lot of money, but well worth it.
