Bit of a loss in the English translation but........
* You should be able to do any ME7.1.1. over OBD nowadays, even with clones, so yes, chip removal is somewhat obsolete nowadays as a method to do them! That comes down to the tools you use at the end of the day!
* With the changes in ecu development/evolution, the 711's can be problematic with all the free stuff on here, only a matter of time before they evolve though, so you'll get Nefmoto stuff doing it all automatically soon when the coders get around to it!
* If your ecu is remapped it could have safety protocols on it to stop some tools from reading/writing easily, depends on the tools and protocols though! Flash on stock file if need be then modify that.....
Once you get through the reading/writing stages there's tons of information on here to modify your ecu...
