electrical error with 2011 C-Max

[auto-hentzschel]

can read the BCMii, but can not write changing to the BCMii. UCDS say me everytime config/write failed.
the car got a new BCMii, because sometimes the engine start button does not work. After installing the new BCMii the IPC show the error children seafty reardoor error. But it works.
fight with this car long time. anyone a idea for me?
