EGR and DPF problems can reduce power, increase fuel consumption, and trigger warning lights. Freedom Truck Repair provides reliable EGR and DPF repairs that restore performance and keep your truck running efficiently.
About Our Heavy-Duty EGR & DPF Repair
Your truck's Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) systems work together to reduce emissions while maintaining engine performance. When either system develops a fault, you may experience reduced power, poor fuel economy, frequent regenerations, warning lights, or forced derates. Freedom Truck Repair delivers EGR & DPF repair to restore engine performance, improve reliability, and keep your truck operating efficiently.
Our Master ASE Diesel Technicians use advanced diagnostic equipment to accurately identify aftertreatment and emissions system faults, ensuring repairs address the root cause rather than simply clearing fault codes.
During our EGR & DPF repair services, we provide:
- Aftertreatment System Diagnostics: We perform comprehensive diagnostics to identify faults within the EGR, DPF, DEF, SCR, and emissions control systems, allowing us to accurately determine the source of performance issues and warning lights.
- DPF Cleaning & Replacement: We inspect diesel particulate filters for excessive soot accumulation, restrictions, and internal damage, recommending professional cleaning or replacement when necessary to restore proper exhaust flow.
- EGR Valve Repair & Replacement: We diagnose and replace malfunctioning EGR valves that can cause rough operation, excessive soot buildup, reduced engine performance, and emissions system failures.
- EGR Cooler Repairs: We inspect and replace leaking or restricted EGR coolers to restore proper exhaust gas recirculation and help prevent coolant loss and engine performance issues.
- DEF & SCR System Repairs: We diagnose DEF dosing problems, NOx sensor failures, DEF pump issues, and SCR system faults that can trigger warning lights or engine derates.
- Regeneration Diagnostics: We diagnose failed, incomplete, or excessive regeneration events by identifying the underlying mechanical or electronic issues preventing the system from operating correctly.
- Sensor & Wiring Repairs: We test and replace faulty temperature sensors, pressure sensors, NOx sensors, wiring, and related electrical components that affect aftertreatment system performance and reliability.
