Info I found on the internet:

As these innovations are still relatively young, it's somewhat unclear if they deteriorate with time. "When initially designed, nobody knew, so airbag manufacturers limited liability to 10 years and car companies did the same," says Mats Oldman of Autoliv, a Swedish company and one of the world's major suppliers of airbags. "That's why some cars still have airbags giving expiry dates."

Oldman says that, in reality, airbags probably last as long as the vehicle itself, unless the explosive powder becomes moist. This is very unlikely and probably only a risk in areas prone to high humidity or torrential rain.

But, says Tom O'Connor of VW, the "lifetime guarantee" generally refers only to airbags fitted in the controlled environment when the car is being built and not necessarily for those installed afterwards. It's down to where the bag was stored and how it was handled.

Peugeot says that, up to a couple of months ago, it recommended that the pyrotechnics in belts and airbags be replaced after 10 years but has now increased it to 15 years. This is probably just as well, as replacing airbags which deployed in an accident is a big and sometimes costly job.
