Porsche Diesel Particulate Filter DPF Regeneration
Supported coding features by PoCOM diagnostic tool https://www.obdtester.com/pocom
What it does
- Initiates active regeneration of the diesel particulate filter (DPF)
- Burns off accumulated soot to restore filter capacity
- Ensures proper exhaust backpressure and engine performance
When it is required
- When DPF soot load is high or regeneration threshold reached
- After prolonged city driving or short trips
- After sensor replacement affecting DPF monitoring
- When DPF warning light or fault codes appear
Conditions that must be met
- Vehicle stationary or per manufacturer procedure
- Ignition ON, engine running at operating temperature
- Stable battery voltage
- Sufficient fuel level
- Diagnostic tool connected (if required)
What happens during regeneration
- Engine parameters adjusted to increase exhaust temperature
- Soot in DPF oxidized and burned off
- Sensors monitor temperature and backpressure
- ECU confirms successful regeneration
If regeneration is not performed
- DPF may become clogged
- Increased exhaust backpressure
- Reduced engine performance
- DPF warning light and fault codes remain
After regeneration
- Verify DPF soot load in live data
- Clear fault codes if present
- Test drive to ensure proper exhaust performance
- Confirm no warning lights remain
