I haven't seen anyone step up to address this Q, so I'll
give it a shot, based solely on memory of what I read
on the quattro list. IIRC, Audi re-evaluated the 10-year 
number and changed it to 14? years.  The light itself 
comes on typically due to a contact ring inside the 
steering wheel becoming worn or corroded with age.
(I think the sensor system looks for some voltage or
resistance, and when it drops below that number,
it triggers the light.)  The warning light can be reset 
with the VAG-COM or similar tool. I think some people 
have cleaned or replaced the ring, but the manual 
givea many warnings about the dangers of accidently
setting off the air bag.  HTH.
