B1016Passenger airbag off indicator lamp circuit

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

How the car detects it

The airbag unit found a fault in the circuit of the lamp that shows whether the front passenger airbag is switched off (for example a short to battery voltage or an open circuit). Volkswagen bulletins name an unplugged lamp connector and, on some 2019-2021 cars, airbag-unit software that needs an update. The airbag itself is not the problem here. 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.
