U1013Airbag unit not coded

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

How the car detects it

The airbag unit has no coding, so it doesn't know the car's equipment. It needs coding with a scan tool, usually after a replacement. 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.
