Off with a bang

[Niall]

The airbag system has shorting protection built in. Even if you had a air bag disconnected and shorted the pins on it, the chance of it going off are incredibly slim. We are just told to be careful of this as it is possible but like i say, incredibly slim.
Most i can think is a faulty side impact sensor. Its not uncommon for air bags to just randomly go off. A guy at work had his drivers one go off on a 4 day old Cee'd lol.
