Possible Symptoms
- Malfunction Indicator Light (MIL) ON
Possible Causes
- Wiring and/or Connector(s) from/to Exhaust Pressure Sensor 1 (G450) faulty
- Hose from/to Exhaust Pressure Sensor 1 (G450) faulty
- Exhaust Pressure Sensor 1 (G450) faulty/incompatible
Possible Solutions
- Check Wiring and/or Connector(s) from/to Exhaust Pressure Sensor 1 (G450)
- Check Hose from/to Exhaust Pressure Sensor 1 (G450)
- Check/Replace Exhaust Pressure Sensor 1 (G450)
- Check Exhaust Pressure Sensor 1 (G450) Compatibility
Special Notes
- This Fault Code often indicates an incorrect/incompatible Exhaust Pressure Sensor 1 (G450) being installed. VAG uses two different types of sensors:
- through MY 2009 = 076-906-051-A (formerly 03G-906-051-A)
- from MY 2010 = 076-906-051-B
If in doubt check the Part Number of the Exhaust Pressure Sensor 1 (G450) and compare it against the Parts Catalog.
- With CBEA and CJAA engines, the factory documentation may show the wrong part location for the Exhaust Pressure Sensor 1 (G450). This sensor is in a foil pouch just behind the oil cap.
