Hi, wondering if anyone can help, I have a 2012 Audi A1 1.6tdi with the standard halogen headlights, however one of my headlights is cracked and the drl is flickering so I'm looking at replacing. I may aswell get xenons if I'm paying 120-140 per headlight for a halogen. I've bought a complete set ballasts, heat sinks, everything. I can't just plug these in and expect them to work and I suspect I'd have to code them on. Has anyone done this and if so, what did you use and how did you do it? I've coded cars before but never audi, I haven't plugged the lights in yet but I'd appreciate any help you can give. Thanks.

Hi, I currently have a 2012 Audi A1 1.6tdi which has the rmc eu headunit without the double sd card slot (which is required for nav install). I have seen a headunit for the same year and model which has 2 slots and was hoping for some advice on doing a retrofit. I have some previous experience with coding cars (mostly bmw retrofits) and as far as I'm aware the headunit would need coding to the car? however I am unsure on whether the nav would then remain active or would need to be coded by an audi dealership (Would they even do it on a retrofit?). Another issue would be that because of my old HU I wouldn't have the Nav cable that plugs into the new HU, is this just an antenna? Has anybody done this retrofit or is it just not worth bothering? If anyone has any knowledge it would be appreciated.
