One of the main reasons I bought the OBDSTAR X300 DP plus (C package) was to do the Opel 2011 Insignia BCM clone the same as in the video.
So successfully done this today!
leave module connected in car, battery charger on the battery and ignition off.
Plug into obd port

Took a lot longer than in the demo video of it on YouTube so definitely need battery charger on the car.
Also needs internet connection to do it.
