I would like to take part in the forum of an experience that had never happened to me before with a (perfectly working) bdm 1251

On edc16cp34 ? success that writing only flash the car fails to start ? needed to do the import of the single flash the modified file bdm complete with the advanced function.... and not ? the state must only this, but? also to correct the checksum by using the appropriate button, why? alone in the auto , despite writing file optimization...... obviously not corrected.

I had never been necessary to use the checksum button or do the import of the flash on the complete file, and rewrite it all......... to you ? ever happened to you ?
