Hi, I just purchased a OBC scanner from Bavaria Technics. The software worked great although I can not match their codes. They claim they use factory fault codes that can be found in service manuals. I am either blind or they are not posted in the manuals. So please please please if anyone knows where I can find factory codes I would appreciate highly. THe codes generated from BT's software are not preceeded with any letter (P's, B's or C's.). BT was no help at all regarding their codes.
