Hi there, as my profile says, been lurking in the shadows for a while. I'm hoping I can get some help getting things figured out on this 2012 C I recently bought. 200k, III. It was advertised as a 2, but it's got the smart key, door handle sensors, p.b start and upgraded stereo. She's got issues, but let's face it; so do I. I hope to get and give help here. Take care guys and gals! Oh and Merry Christmas/Happy Holidays.
