I have an A rev ce module on my 54 audi a3. I just installed a set of bi xenon. But my ce module does not support bi xenon. So I was thinking of upgrading from A to K, that came on 2007 or sumetin. What is the procedure on replacing this? It aint just plug and play, right? How do I code the new one so that the car sees it as an K rev? Searched everywhere but cant find a guide..
