Restore Performance With Professional EGR & DPF Repair

Prompt diagnostics and repairs help protect your engine, reduce unnecessary downtime, and keep your truck operating reliably. Our technicians identify the real cause of the problem and recommend the repair that gets you back on the road as quickly as possible.

Complete EGR & DPF Repair Services

Your EGR and DPF systems work together to reduce emissions while keeping your engine operating efficiently. Carbon buildup, failed sensors, restricted filters, or cooling issues can quickly lead to reduced power, poor fuel economy, repeated regenerations, and costly downtime.

Our technicians diagnose the root cause before replacing parts. Using professional diagnostic equipment, we repair EGR and DPF systems to restore performance, improve reliability, and keep your truck operating within emissions requirements.

EGR System Repair

The Exhaust Gas Recirculation (EGR) system recirculates a controlled amount of exhaust gas back into the engine to lower combustion temperatures and reduce NOx emissions. When components begin to fail or become restricted with soot, engine performance and fuel efficiency suffer.

Our EGR repairs include:

• EGR valve diagnostics and replacement
• EGR cooler inspection and repair
• Carbon buildup removal
• Sensor testing
• Cooler leak diagnosis
• Flow testing
• System performance verification

DPF Cleaning & Replacement

Your Diesel Particulate Filter (DPF) captures soot before it leaves the exhaust system. As the filter fills, it relies on successful regeneration cycles to continue operating properly. If regeneration fails or the filter becomes excessively restricted, engine performance declines and the truck may enter a derate.

We provide:

• DPF diagnostics
• Forced regenerations
• DPF cleaning
• Differential pressure testing
• Sensor replacement
• DPF replacement when cleaning is no longer effective

Common Signs Your EGR or DPF Needs Repair

Many emissions problems begin with small performance changes before becoming major failures. Early diagnosis often prevents expensive repairs and extended downtime.

Common warning signs include:

• Check engine light
• Frequent or failed regenerations
• Engine derates
• Reduced power
• Excessive black smoke
• Poor fuel economy
• Increased exhaust back pressure
