BMW Z4 e85 Airbag light

Hey guys, I have been following and actively reading the sub for a longer time now and I might need your advice.

I just got a Z4 3.0 with 80k km. It’s not my first bmw or the first bmw that needs some love.

Since a haven’t worked on a old BMW for a long time I don’t have a working bmw diagnostic sw.

I did scan the car for codes with an ordinary scan software for independent shops and i got the following error codes: 93B7, 93C2, 93C7, 93B1

After some internet searches I think it might be an issue with the „B-Pillar“ module?

I would appreciate if someone can help me out here and if someone is willing to help me setup my long lost bmw software i would love that.
