The air-bag wasn't "New", it was an eBay item from a 2010 206. It worked fine for about 2 weeks and then started to come on. It did go off one day and whilst the ignition was on I giggled the wires underneath the seats & moved them back and forth. The light only came on again when I turned the wheel, so it seems like a new com2000 is in order.
Just wanted to make sure because a new one is around ?300!
