B1000Driver front airbag igniter circuit

• Volkswagen group code · Airbag (SRS)
• Lights a warning lamp

How the car detects it

The airbag unit measured a fault in this firing circuit. The failure-type byte says which: resistance too high (most often a loose connector or a broken wire), too low, or a short circuit. For this circuit Volkswagen names a torn clock spring (the coiled ribbon cable behind the steering wheel) as a known cause and extended its warranty on many 2010-2018 cars, Golf included. While an airbag fault is stored, the affected airbag or pretensioner may not deploy in a crash. Have it repaired before relying on it. Never probe airbag connectors with a meter: that can fire the airbag.
