Special Notes

  • Skoda Superb (3U) & VW Passat (3B) (Engine Codes: BGW, BSS, BWW) had issues with faulty Exhaust Pressure Sensors (G450), they were defective from factory and due to a leaking sealing the measured values were incorrect and resultet in wrong calculated particle filter load and unsuccessful regeneration cycles.
  • 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.
