Hi all,
Now, after all this time, I can proudly say that all my airbag issues are solved and my reader shows no error codes.
The problem was with the connectors of the rotary coupler, they had a poor union with the airbag. I checked all with a voltmeter and after that the ignition switch error went away.
I'd particulary want to thank FlyingScot that helped me so much.
Thank you guys, finally I could pass the MOT without worries.
