Our Services

At D&I DPF Cleaning Fresno, we specialize in professional DPF cleaning, DPF repair, emissions system diagnostics, and full diesel truck repair services for owner-operators and fleets throughout California’s Central Valley.

Your Diesel Particulate Filter (DPF) plays a critical role in emissions compliance, engine efficiency, and overall truck performance. Over time, soot and ash accumulate inside the filter, restricting airflow and causing:

  • Frequent regens

  • Loss of power

  • Poor fuel economy

  • Check engine lights

  • Engine derate

Advanced DPF Cleaning Technology

We use industry-leading equipment from Filtertherm to ensure thorough, measurable, and repeatable cleaning results.

Our professional cleaning process includes:

  • Controlled thermal baking to remove carbon buildup

  • Precision air cleaning to extract ash

  • Full inspection before and after service

  • Restoration of proper exhaust flow

This is not a quick blow-out service. Our system is engineered to clean your DPF the way it was designed to be serviced — restoring performance and extending filter life.

DPF CLEANING

Not every DPF issue requires replacement — but when it does, it needs to be done right.

We provide:

  • DPF diagnostics

  • DPF removal and installation

  • DPF replacement (when structurally necessary)

  • Crack and failure assessments

  • DOC service and replacement

If your DPF core is melted, cracked, or beyond safe cleaning limits, we offer honest recommendations and high-quality replacement solutions.

DPF REPAIR

Many DPF problems are symptoms of larger emissions system issues. Our experienced technicians diagnose and repair the entire system to prevent repeat failures.

We service and replace:

  • DEF system components

  • DOC (Diesel Oxidation Catalysts)

  • NOx sensors

  • Pressure sensors

  • Temperature sensors

  • EGR-related components

  • Clamps, gaskets, and exhaust hardware

For emissions parts and components, we trust Redline Emissions Products — known for durability and long-term performance in heavy-duty diesel applications.

We do not cut corners. We install reliable parts designed to keep your truck on the road.

DPF PARTS

While DPF cleaning is a specialty, we provide broader diesel truck repair services to support owner-operators and fleet vehicles.

Our services include:

  • Emissions system repair

  • Sensor replacement

  • DEF diagnostics

  • Exhaust system service

  • General diesel repair support

Because we’ve spent over 25 years in the transportation industry, we understand the operational pressures truck owners face daily. Our goal is to fix it right the first time — and get you back on schedule.

TRUCK REPAIRS

Some DPF cleaning services focus on speed alone. We focus on speed and precision.

Our Process

At D&I DPF Cleaning Fresno, we keep the process simple, clear, and built around minimizing downtime. With over 25 years in the transportation industry, we understand that every hour your truck sits is money lost. Here’s exactly how our process works:

  • You contact us by phone or through our website form.

    • Tell us what your truck is experiencing (check engine light, frequent regens, derate, loss of power, etc.)

    • Provide basic truck details (make, model, mileage)

    • Let us know if you're an owner-operator or fleet manager

    From there, we’ll either call you back or email you promptly to discuss next steps.

  • When your truck arrives, we perform a complete DPF and emissions system evaluation.

    This includes:

    • Scanning fault codes

    • Inspecting the DPF for cracks or melting

    • Checking sensors (NOx, pressure, temperature)

    • Determining whether cleaning or replacement is needed

    Not every DPF needs to be replaced. If it can be professionally restored, we’ll recommend the most cost-effective solution.

    You’ll receive a clear estimate and invoice before any work begins.

  • If cleaning is approved, we use advanced equipment from Filtertherm to restore your filter to proper operating condition.

    Our professional process includes:

    • Controlled thermal baking to remove soot and carbon buildup

    • Precision air cleaning to extract ash

    • Measured airflow verification

    • Final inspection before reinstall

    This is not a quick blow-out service. It’s a controlled, engineered cleaning process designed for long-term performance.

    If replacement parts are required, we use high-quality emissions components from Redline Emissions Products — because we do not cut corners.

  • After cleaning or repair:

    • The DPF is reinstalled properly

    • Sensors and components are secured

    • Fault codes are cleared

    • System performance is verified

    We make sure everything is functioning correctly before your truck leaves our shop.

    For fleet clients, we can also coordinate multiple units, structured invoicing, and scheduled maintenance rotations to reduce future downtime.
