Diesel Particulate Filter (DPF) Service

Your diesel particulate filter (DPF) plays a critical role in reducing emissions and maintaining your engine’s performance. Over time, soot and ash build up inside the filter, restricting exhaust flow and causing power loss, increased fuel consumption, and potential engine damage.
At Rob’s Automotive Repair in Clackamas, Oregon, our ASE-certified technicians specialize in DPF cleaning, diagnostics, and service for light-duty diesel vehicles and fleets.

What Is a Diesel Particulate Filter (DPF)?

The diesel particulate filter is part of your vehicle’s exhaust after-treatment system. Its purpose is to trap soot and ash particles from diesel exhaust, ensuring your truck meets EPA emissions standards. As the filter fills with soot, it must either regenerate (burn off the buildup) or be professionally cleaned to maintain efficiency.

If left unattended, a clogged DPF can lead to:

  • Reduced engine power and performance
  • Poor fuel economy
  • Warning lights on the dashboard
  • Higher exhaust temperatures
  • Potential turbo or engine damage

When you see your diesel particulate filter warning light, don’t ignore it — schedule service right away to prevent further issues.

Our DPF Cleaning and Service Process

At Rob’s Automotive Repair, we use advanced tools and techniques to restore your DPF to optimal condition. Our technicians inspect, diagnose, and clean filters safely and effectively, using industry-approved equipment.

Our DPF service process includes:

  1. Comprehensive inspection and blockage assessment
  2. Filter flow testing to determine soot and ash buildup
  3. Professional DPF cleaning using methods such as:
    • Hydrodynamic cleaning (using fluid jets to remove soot buildup)
    • Thermal baking (heating the DPF in a specialized furnace to burn off trapped particulates)
  4. Drying and flow testing to ensure proper airflow and functionality
  5. Reinstallation and system verification for proper sensor readings

These steps ensure your diesel truck or fleet vehicle maintains performance, efficiency, and compliance with emissions standards.

    I'm late to review Rob's, as they took care of me back in August, but these guys are amazing!!! Carter was the main employee I spoke with over the phone and he was phenomenal. He also came in on his day off to make sure I had … read more my car secured in a safe place until they opened. Corey also really helped when I came in personally and by going through some paperwork to ensure I wasn't being screwed over by the company I had been going to the last several years (which it turned out i kind of had been). Carter and Corey worked together to find me the best ways to handle the situation and have me honest suggestions without making me feel manipulated into paying for maintenance through they're company - they were there to help and make sure that I was safe while driving my vehicle. While being very professional and knowledgeable, they went up and beyond what I could have hoped for. The company understands that life happens and they do everything (within reason) to work with your time and budget to make sure that their clients are well taken care of and that the work that they do is thorough and accurate.I HIGHLY suggest using Rob's Automotive for your vehicle needs because of their honesty, hard work and their excellent customer service.Thank you again, especially Carter and Corey, for helping me get through a rough time with my little car and helping me feel confident that I made the right choices on how to handle my car issues. I will absolutely be coming back!
