I've got a 2006 facelifted CC, and lost a dipped beam bulb a few days ago. Spent a while reading up on how to change them having read the horror stories.

I think they have changed the design of the bulb holders on the dipped beam. The only spring clip is now on the main beam. I got some pictures, and wrote up some hints on the CC Forum, hopefully they may be of use to the folks on here. Made it much easier than I was expecting!
