Have the ability to disable the front passenger airbag?

I believe it's an option when you buy the car new to have that facility installed, but await more knowledgable people than I for definite answer

You can turn the Passenger Airbag off on the Touareg produced from 2002-2010. There's a switch operated by the ignition key located by the gearlever.

I cannot comment on the current 2010 onwards model.
