Q: I have a 2004 Audi A4 convrt. I am concidering putting an HID kit into the cars stock projectors. Will this cause any warning lights to come on? Thanks!
A: Probably. You will need a VAG COM computer to defeat the bulb failure light. However, if you get S4 HID's or RS4 HID's with the complete wiring harness and ballasts you may be able to not worry about it.
