Manual cleaning instructions – heavily clogged DPF (>70% soot)

1. Remove the DPF filter from the vehicle.
2. Check the condition of the filter (cracks, melting, oil). If damaged – replace.
3. Prepare the Wynn’s Off-Car DPF Cleaner solution.
4. Immerse the filter completely and leave for 90–120 minutes (for very heavy contamination – up to 8 hours).
5. Gently move the filter during soaking.
6. Rinse thoroughly with warm water from both sides until the water runs clear.
7. Dry with low-pressure and low-temperature compressed air.
8. Reinstall the filter, connect sensors, and clear any errors in the controller.
9. Perform a test drive or forced regeneration to confirm proper operation.

Notes

• Use personal protective equipment (gloves, goggles, ventilation).
• Do not use a pressure washer or high-pressure air directly on the core.
• Dispose of used fluid and rinse water according to regulations.
• Record the cleaning in the vehicle's service history.
