I got the HID kit for the fog lights of my C4 but couldn't figure out how to change the bulbs. I might get to the bulb on driver's side but it's impossible on the passenger side. How did you guys do it?
Really? You have to remove the bumper, sounds complicated enough, to change the bulbs? Any other way around?
You need to take the plastic cover underneath the front fenders off. That is how you can get an access to the bulbs. Detailed description is given in the user's manual, somewhere at the end. I believe in the pink section.
