18434/P2002/008194 - Particle Filter Bank 1: Malfunction

Possible Symptoms

  • Malfunction Indication Lamp (MIL) active

Possible Causes

  • Exhaust Pressure Sensor (G450) faulty
  • Diesel Particle Filter (DPF) faulty

Possible Solutions

  • Check/Replace Exhaust Pressure Sensor (G450)
  • Diesel Particle Filter (DPF)

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.
