DPF Repair
The diesel particulate filter traps soot so your truck can meet emissions standards, but it needs care to keep working. When it clogs, cracks, or stops regenerating, you'll see warning lights, lose power, and possibly end up in a full derate. I-55 Truck & Trailer Repair repairs DPF systems at our shop on I-55 in Crawfordsville AR and on the road across Memphis & West Memphis. We handle everything from a quick regen to a full filter replacement, so you can get back to work at full power.
Why Choose Us
Getting to the Bottom of DPF Trouble
A clogged DPF is often a symptom of something else, like a bad sensor, a leaking injector, or too much idle time. Our ASE certified mechanics check the whole aftertreatment system to understand why the filter is struggling. That way, you're not paying for a cleaning or replacement only to face the same problem again. As a truck repair shop with 25 years of diesel experience, we know how to keep your DPF system healthy for the long haul.
What We Offer
Every DPF Service Your Truck Might Need
From early warning signs to a complete shutdown, we can handle DPF problems at any stage. We start with diagnosis, then recommend the most cost-effective fix. Here's what our DPF repair service includes:
DPF Diagnostics: We check soot and ash levels, pressure readings, and fault codes to understand the filter's condition. This tells us exactly what service your DPF needs.
DPF Cleaning: Ash builds up over time and can't be removed by regeneration. Professional cleaning clears out that ash and restores exhaust flow.
Forced Regeneration: When soot builds up faster than the truck can burn it off, we run a forced regen. This clears the filter and gets your engine back to full power.
DPF Replacement: Cracked, melted, or badly plugged filters may need to be replaced. We install a new DPF and check related parts to protect it.
DOC and SCR System Service: The diesel oxidation catalyst and SCR system work closely with the DPF. We inspect and service these components so the entire aftertreatment system works together.
Sensor and Wiring Repair: Faulty pressure and temperature sensors can cause false readings and failed regens. We test and replace sensors and repair damaged wiring.
Derate and Check Engine Light Diagnosis: DPF problems are a common cause of derates and warning lights. We find the fault and fix it to restore normal power.
24/7 Roadside DPF Support: If a DPF problem shuts you down on the road, our team can respond day or night. We'll run a regen on-site or get your truck to the shop.
Preventive DPF Maintenance: Regular checks and scheduled cleanings help prevent surprise derates. We'll recommend a service schedule based on how your truck is used.
Frequently Asked Questions
What are the signs of a clogged DPF?
Common signs include a DPF warning light, frequent regens, reduced power, higher fuel use, and a derate. Ignoring these signs can lead to more expensive repairs.
What's the difference between DPF cleaning and a regen?
A regen burns off soot using high exhaust temperatures. Cleaning removes ash, which can't be burned off and builds up over time.
Why does my DPF keep clogging?
Frequent clogging is often caused by excessive idling, short trips, faulty sensors, leaking injectors, or EGR problems. Fixing the root cause helps your DPF last longer.
Can a DPF be repaired, or does it always need replacement?
Many DPF problems can be solved with a regen or cleaning. Replacement is usually only needed if the filter is cracked, melted, or too damaged to clean.
