I have a 2002 VW Beetle and yesterday my car wouldn't start and the air bag light stayed on. I finally got it started today and the airbag light goes off for a little bit and then comes back on and stays on, I pulled my car back to my house and didn't drive it to work, what would be the easiest solution to this problem? Is it the battery? This has never happened to me before and I have had this car a little over a year. Also would it be safe to drive?
