The QUESTION of what will happen to old air bags is a good one.
I have asked the same one as my son drives a 1986 190E & the air bag is now 1 year past the "good life" date.
An MB engineer told me that there isn't any way that it would go off by itself, however he said that in an accident it may not deploy completely due to the generator being OLD.
