The first problem with MPPS v12 box version of the forum and MB W203 C200 115hp 2002.
The situation ? this (I took risks whereas the car ? throw it away):
ID ECU with the protocol EDC15C6 - does Not work!
Read on EDC15C6 - does Not work!
Write ORI with the same protocol - it Works!!!
Why does not the law but the writes? I have used the CTEK MXS10 and the voltage was 13.8 v, not c'? was to read it, even trying different protocols, depends on what?
