I know there will be an Airbag error when you disconnect the starter battery while the ECU's are still active. This is a typical scenario when you put your car in a shipping container, the guys who are handling this just disconnect all the batteries. Then when unboxing the car at it's destination harbor, you'll have this annoying Airbag error showing up all the time - could only be cleared at an INEOS workshop.
I think I'll try to replicate this Airbag error - let's try if I can clear it by my own now!

- that would be a great use case !
