I need to disable the passenger side airbag so that I can fit a rear-facing child seat.

Does anybody know how I can do this?

 

Don't think you can - well not so the dealers say!

 

Nope...... Can't disable the airbag on my bugeye and the little fella goes in the back and cries.

Might be different for the Blobeye onwards as they have some ISOFIX points......... in the back..LOL

Midlife.....

 

Unplug it and plug a 2ohm resistor in its place. And i didn't tell you this.
DO not try and measure the resistance of the airbag as it could go off.
