B2013Airbag unit: end-of-line programming missing

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

How the car detects it

The airbag unit lacks the vehicle-specific data it normally gets at the factory, typically after it was replaced or updated. A dealer-level tool must load that data online. 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.
