Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Clear Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Navigate to the DPF codes and erase them.
Disconnect the scanner after clearing codes.

3. Perform Active Regeneration

Start the engine and allow it to reach operating temperature.
Drive the vehicle at a constant speed of 40-60 mph for at least 20 minutes to initiate passive regeneration.
Monitor the DPF warning light; it should turn off after successful regeneration.

4. Replace DPF Pressure Sensor (if faulty)

Locate the DPF pressure sensor, usually near the DPF unit.
Disconnect the electrical connector and remove the sensor using a socket wrench.
Install the new pressure sensor and reconnect the electrical connector.
Ensure all connections are secure.

5. Inspect and Clean DPF (if still blocked)

Remove the DPF from the vehicle using a socket set, ensuring to detach any clamps or sensors.
Use a specialized DPF cleaning solution to clean the filter, following manufacturer instructions.
Rinse thoroughly and allow to dry before reinstalling.
