When EGR and DPF problems are left unaddressed, it leads to power loss, failed regenerations, and expensive engine damage. Legacy Road Service provides keeps your emissions systems functioning and your trucks running clean.

Truck Aftertreatment Repair Throughout the Southeast

The aftertreatment system on a modern heavy-duty diesel truck plays a critical role in both emissions compliance and engine performance. When components in this system begin to fail, the effects show up quickly across the entire powertrain.

A clogged DPF typically shows up as reduced power, higher fuel consumption, frequent regens, and warning lights. A faulty EGR valve often causes rough idling, black smoke, poor throttle response, and EGR-related fault codes.

At Legacy Road Service, our technicians handle the full range of EGR and DPF service and repair, including:

  • Exhaust gas recirculation for trucks diagnosis, cleaning, and repair
  • EGR valve replacement for trucks for stuck, leaking, or electronically failed valves
  • EGR system repair for trucks covering coolers, sensors, and actuator faults
  • EGR system cleaning for trucks to remove carbon buildup, restricting flow and response
  • DPF cleaning for trucks, including soot removal and flow restoration
  • Truck DPF repair for cracked, melted, or heavily contaminated filter substrates
  • Forced regeneration when passive and active regeneration cycles have failed to clear the filter

What Makes Legacy Road Service Different?

Aftertreatment repairs require diagnostic precision and hands-on familiarity because the system's behavior varies across different truck platforms. Keeping EGR and DPF systems in good working order protects the engine from the downstream damage that follows when these systems are neglected or bypassed improperly.

Reasonable Pricing: EGR and DPF repairs can range from a cleaning service to a full component replacement. Our pricing is honest and clearly communicated upfront so operators can make informed decisions without pressure or surprise charges.

24/7 Availability: An aftertreatment fault that triggers a derate can limit a truck to reduced power at any hour. Our around-the-clock availability means those situations get addressed promptly rather than sitting until the shop opens the next morning.

White Glove Service: Every aftertreatment repair begins with a proper diagnostic scan and system inspection. We identify the root cause, walk the operator through the findings in plain terms, and document all work completed for fleet maintenance records.

What Is the Main Cause of EGR Failure?

The most common cause of EGR failure in heavy-duty diesel trucks is carbon buildup inside the valve and cooler passages. Over time, exhaust soot and oil vapour deposits restrict flow and cause the valve to stick or respond erratically. Extended idling, short-trip operation, and neglected air filter maintenance all accelerate the rate of carbon accumulation.

What Are the Signs of a Bad DPF?

A failing or clogged DPF typically causes a noticeable drop in engine power, increased fuel consumption, more frequent or incomplete regeneration cycles, and a DPF warning light on the dashboard. In severe cases, the engine may enter a derate mode that limits speed and power output until the filter is serviced or replaced.
