Rear head airbag

[zuvarak]

Hello everyone!

First post!

So here's the deal: Some time ago I bought a 2005 e53 3.0D with ~217k miles.
It's got relatively good service history, but it needs some love.

It apparently had a slight collision or smth, so the left rear door was painted. Car frame itself was not damaged, but the rear head airbag had gone off. In order for me to pass inspection this month, I need to deal with the airbag light in my dash.

I took the headliner slightly apart just so see what I'm dealing with and the previous owner or the workshop just shoved the airbag back in and called it quits.

Could someone help me with the following?
1. If I was going to buy a replacement airbag, plugged it in and cleared the code, will the light stay off or is there something else to it?
2. If I unplug the current airbag, deactivate it with NCS Expert or something else and clear the code, will it stay off as well? - I tried just clearing the code, the light in the dash disappears for a second and comes right back, which is correct, as it understands that it's plugged in and has gone off already.

Any feedback is appreciated!

Best regards
Arthur
