Applies to: 2.0D / 2.2D diesel (Ford Duratorq TDCi), 2003-2009 · Confidence: Platform code set + documented field failures
Common causes
- DPF blocked with soot/ash
- DPF cracked or gutted
- Differential pressure sensor or pipes faulty
- Repeated failed regenerations from short journeys
Quick checks
- Scan access: Generic OBD-II scan tool / WDS-IDS
Typical fixes
- Check the DPF differential pressure sensor and its pipes before condemning the filter
- Perform a forced regeneration with a capable tool
- If ash-loaded, have the DPF professionally cleaned or replaced
- Advise the owner that regular sustained motorway runs are needed for passive regeneration
