I'd like to replace the HID bulbs on my A7 to have them brighter (I know it only looks better not really "brighter", anyway). However, my dealer can't install any non-audi part. On top of that, it seems there's no on-line guidance that I can follow. Does anyone know how to do replace the HID bulb?
Do you mean that you want to change the color or do you want to increase the wattage? You probably shouldn't try to increase the watts. Todays cars use small wires and increasing the load results in toasted wires and connectors.
You should be able to find a "Change the bulb" video on YouTube.
I found the website below when searching info about my A7 hid issue. Although I haven't had it done, the site shows lots of info/pics about our A7s. I don't know if it's been posted here. Just to share the info and hope it helps someone someday.
