16785/P0401/001025 - Exhaust Gas Recirculation (EGR) System: Insufficient Flow Detected
Possible Symptoms
- Malfunction Indicator Light (MIL) ON
- Reduced Exhaust Gas Recirculation (EGR)
- Reduced Power Output/Engine running rough
- Increased Emissions
Possible Causes
- Exhaust Gas Recirculation (EGR) Flow restricted/clogged
- Exhaust Gas Recirculation (EGR) Valve stuck closed/leaking/faulty
- Wiring and/or Connector(s) from/to Exhaust Gas Recirculation (EGR) Valve faulty
- Exhaust Gas Recirculation (EGR) System faulty
Possible Solutions
- Check/Clean Exhaust Gas Recirculation (EGR) System
- Check/Replace Exhaust Gas Recirculation (EGR) Valve
- Check Wiring and/or Connector(s) from/to Exhaust Gas Recirculation (EGR) Valve
Special Notes
- Some TDI-CR engines have a filter for the EGR that can become restricted and cause a "Insufficient Flow" code.
