Can you turn off the passenger airbag on the early new Beetles I know you can on the later models?
It was not required by law in the earlier models and it is not
something they wanted people messing with so no I dont think there
is a way.
New models will have a weight sensing switch in the seat that
will cut it off under a certain size.
In vehicles where there was an option for the child to sit in
the rear a shut off was not required.
