Airbag indicator light

The most common cause of an airbag light that I've found is that one of the underseat airbag connectors was pulled slightly apart when the seat was put too far back. This strains the connection and opens the connector momentarily, just enough to trip the light. Your airbags are still fully functional - the light is a warning that there was an open connector at one time.

You don't have to go to a dealer if you have a laptop computer. You need the diagnostic software that Audi uses (called VagCom). You can download it legally and free from www.ross-tech.com, and you'll need a $20 OBDII interface cable for hooking the car up to the computer (available on eBay). With this, you can scan the car and see which airbag tripped the fault light.

If it's an underseat bag, look under the front of the seat - you'll see harness connections facing you. The yellow one is the airbag connector. Use small zip-ties and zip it tightly together (don't damage the wires!). Afterward, use VagCom to turn off the light, and you should be good to go.

Or you can go to a dealer and have them take three minutes to turn it off...and charge you an hour's labor. Your call:)

Has to go to dealer to be reset. There could be many reasons your light is on: damaged wiring, faulty component, or even had a flat battery and the capacitor that deploys the airbag has been run flat.
the light means the system has been de-activated and may not deploy in the event of an accident.
