Hi, I just joined the forum and I am really happy that I found this post - it seems like there are a lot of people here who know about CCC conversion...
I recently purchased a CIC from ebay in the hopes of converting my CCC to a newer version (I have 2007 335i). Ebay seller promised that it will work, but I keep getting red screen and can't make it work, the seller is not being helpfull at all. It's been a nightmare.. Does anyone have any clue as to what might be wrong? Is it the CIC? Is it the vehicle? Would dealer be able to help? Any help will be appreciated!
