DPF System Diagnostic & Repair

DPF System Diagnostic & Repair

DPF System Repair Services in Detroit MI

When soot and ash clog up your diesel particulate filter, it’s not just the engine that suffers—it’s your fuel mileage, power, and time on the road. Over time, that buildup strangles performance and burns a hole in your budget.

Diesel Highway INC. focuses solely on keeping your DPF clean, clear, and flowing right. Our hands-on DPF System Repair Services in Detroit MI, are designed to restore engine response, extend component life, and keep your diesel rig hauling strong.

This isn’t speculation or quick patch jobs. We use industry-proven inspections that include:

  • Backpressure Testing to read how much airflow is blocked inside the filter
  • Sensor Diagnostics to check for irregular temps or bad readings
  • Flow Rate Checks to measure how freely air is moving through the filter

Once we get real numbers, we give you a clear look at what your system needs—not what sounds good.

From Clogged to Clear: A True Filter Reset

Once we’ve pinned down the issue, we clean deep—not just surface fluff. Our shop uses a mix of powerful cleaning techniques based on your filter’s condition. Every DPF gets treated with care that earns you longer run times between regens and better response behind the wheel.

We rely on the most effective restoration methods, including:

  • Thermal Bake Cleaning – filters are slowly heated in a controlled chamber to remove hardened ash and soot
  • Air Knife Blasting – compressed air slices through dry buildup that clogs the filter walls
  • Hydro Wash Process – water pressure removes leftover particles stuck in hard-to-reach filter channels
  • Ultrasonic Cleaning (when needed) – soundwaves break apart fine debris in the filter core

After every Cleaning, your DPF is re-checked for airflow and backpressure to make sure it’s ready to perform like new. No assumptions. No shortcuts.

When Your Truck Breathes Better, You Earn Better

Detroit keeps diesel trucks moving, and our team keeps their DPFs breathing clean. With years of daily hands-on experience under the hood, we know what it takes to keep your truck pulling with force, not fighting for air.

Our DPF System Repair Services in Detroit MI, are built for those who rely on their trucks to earn. Whether you’re hauling across state lines or making runs inside the city, you need a clean filter to keep rolling without warning lights or power dips.

You’ll notice the difference when your throttle responds quicker, your engine runs cooler, and those regen cycles happen less often.

Here’s what you gain:

  • More pulling power without lag
  • Lower fuel usage and fewer regens
  • A longer-lasting filter and better engine flow
  • Confidence that your DPF was cleaned right the first time

Diesel Highway INC. keeps things real, honest, and clear. Just solid work that helps your truck stay out of the shop and on the road where it belongs.

Why Choose Us

Stop Replacing Filters Too Soon

Many filters get thrown out when they could’ve been saved. Our cleaning process restores life to your DPF instead of pushing replacements. We help you avoid spending thousands when a solid clean is all it takes.

End the Cycle of Warning Lights

Warning lights that come and go leave drivers guessing and stressed. Our scan tools don’t just clear codes—they find out why they appeared. That way, your dash stays clear, and you’re not pulled off the road unexpectedly.

Avoid Roadside Shutdowns

An unchecked DPF can trigger forced regens or derate mode at the worst time. We catch early signs of trouble during diagnostics, so you’re not left stuck on the side of the highway when you’re trying to make a deadline.

FRequently Asked Questions

If flow stays low after cleaning or pressure readings seem off, the filter might be damaged inside. We check for these signs during diagnostics.

Not really. Problems can build slowly. Early checks can catch things before they get costly.

Clearing codes without fixing the cause makes things worse. The buildup stays and keeps growing.
