Problem:
Today I tried to collect data on the Mercedes W204 ignition switch, and the CGDI Prog MB programmer returned error code E127 ( CGMB equipment is demaged, error code: E127) . EIS data reads normally, keys can be saved, keys can be generated (from previous data). Has anyone had this problem? I can’t save the elv emulator either, but I think it’s an emulator problem.
Solution:
This error is the result of a flat CR2032 battery. After replacement, you need to contact technical support, they upload the firmware to the programmer via Teamviewer.
