Did you smoke him out, get him drunk, and feed him a lot of food? If not, I have no idea why...

You can't reset an airbag light... It means that there is a problem with the airbag system.. Have it checked out for possible electrical problems... If by chance you get into an accident, the airbags won't deploy... Be careful

Try and unplug then plug back in the EGR sensor.. If that doesnt fix it then you need to replace the EGR tube itself..
