Shop vacuum
Safety goggles and gloves

2. Remove the DPF

Sub-step 1: Raise the vehicle using a jack and secure it with jack stands.
Sub-step 2: Locate the DPF in the exhaust system.
Sub-step 3: Disconnect any electrical connectors and sensors attached to the DPF.
Sub-step 4: Remove the bolts securing the DPF to the exhaust system using a socket set.
Sub-step 5: Carefully detach the DPF from the vehicle.

3. Clean the DPF

Sub-step 1: Use a shop vacuum to remove loose soot and debris from the DPF.
Sub-step 2: Apply DPF cleaning solution according to the manufacturer's instructions.
Sub-step 3: Allow the cleaning solution to soak for the recommended time.
Sub-step 4: Rinse the DPF with clean water, ensuring all cleaning solution is removed.
Sub-step 5: Allow the DPF to dry completely before reinstallation.

4. Reinstall the DPF

Sub-step 1: Position the cleaned DPF back onto the exhaust system.
Sub-step 2: Secure the DPF with the bolts removed earlier, and torque them to the manufacturer's specifications.
