Peugeot Traveller Callback Code MGJ

Servus Forum, currently has a problem with my Peugeot Traveller. There is a callback action from the German Federal Motor Vehicle Agency (KBA) with the code MGJ. I was in two different Peugeot workshops. No one was able to play the new software. It was always called “There are problems in the system.” I picked up my bus every time without repairing defects. I also wrote the customer service several times. It was also called here only errors in the system.. ?? Somehow it is interested The deadline for the KBA was 06.06. In the workshops I am short of the 05.06. long speech. My question. Does anyone have any problems with the mentioned callback code MGJ? Or was there no problem? Since the callback action also concerns the identical Opel, Toyota and Citroen buses, can such a software also be played from there? I am just overwhelmed and helpless, feel with my P roblem left alone. Greetings and thanks for reading.
