HOW TO CLEAN A DPF/CAT UNIT ON A VEHICLE USING BAC101

Cleaning a Diesel Particulate Filter (DPF) or Catalytic Converter (CAT) unit using BAC101 is a critical maintenance task to ensure a vehicle or engine’s emission system operates efficiently.

 Here is a comprehensive guide detailing each step of the process.

 Tools and Materials Needed

• Safety gloves and goggles
• BAC101 spray pump
• Protective covering or tarps
• DPF fitting/tool kit 4mm/6mm (if necessary)
• Screwdriver, wrench or grips (for removing and reinstalling components)
• Disposable rags or paper towels

1. Preparation

• Safety First: Wear safety gloves and goggles to protect yourself from the chemical cleaner.
• Vehicle Positioning: Park the vehicle on a flat, stable surface. Ensure the engine is off and the exhaust system is cool to avoid burns.

2. Access the DPF Unit

• Locate the DPF: The DPF unit is typically found in the exhaust system, either close to the engine or underneath the vehicle.
• Remove Necessary Components: Depending on your vehicle model, you might need to remove protective covers or components to access the DPF. In many instances, you can access entry to the DPF through the o2 or pressure sensor lines, this gives much easier access through the engine bay, saving time and making the process far simpler.

3. Application of BAC101

• Mix Part-1: To start, add 200ml of “A/B” chemical to the spray pump and fill with water to the 1.75l mark.
• Shake the Cleaner: Before use, shake the spray bottle thoroughly to ensure it is well-mixed.
• Insert the Cleaner: Depending on the vehicle, you may need a 4mm or specific DPF cleaning tool to insert the cleaner into the DPF unit.
• Spray the Cleaner: Pump the spray bottle 15-30 times to build pressure, apply the cleaner directly into the DPF through the designated access port or remove the temperature or pressure sensor to insert the cleaner. Ensure even distribution by spraying in intervals.

4. Let the Cleaner Work

• Soak Time: Allow the chemical cleaner to work, typically 15 minutes. This period allows the cleaner to break down soot, carbon and ash deposits inside the DPF.
• High Soot/Ash levels: Allow a longer period of cleaning, 30-60 minutes will give the process enough time required to break down the high levels of contaminant and allow for a thorough clean.
• Run the Engine: Start the engine and allow it to idle for 15 minutes in order for the chemicals to pass through the DPF and Cat cores.
• Repeat Pt 3/4: Repeat sections 3 and 4 with part “C”. Whilst Part A&B are designed to break down the contaminants within the DPF and Catalyst filters, part C is a “binding” agent designed and purposed to combine the ash, carbon, soot and oil within a slurry that exits the engine when running and “loading” pressure within the exhaust system.

5. Reassembly and Final Checks

• Reinstall Components: Carefully reinstall any components you removed to access the DPF unit.
• Inspect for Leaks: Check all connections and ensure there are no leaks around the sensors, DPF or exhaust system.

6. Regenerate the DPF

• Drive the Vehicle: Start the engine and drive the vehicle at highway speeds for at least 20-30 minutes. This process helps in heating the DPF, allowing the cleaner and loosened particles to be expelled.
• Monitor Dashboard Indicators: Pay attention to any warning lights on the dashboard. If the DPF warning light remains on, it may indicate the need for a diagnostic reset.

7. Post-Cleaning Maintenance

• Regular Inspection: Regularly check the DPF and related components to ensure they are functioning properly.
• Scheduled Cleaning: Incorporate DPF cleaning into your vehicle’s regular maintenance schedule to prevent excessive buildup and maintain optimal performance.

 By following these steps, you can effectively clean a vehicle’s DPF and Catalytic unit using BAC101 spray cleaner, ensuring better engine performance and compliance with emission standards.
