Modern diesel engines rely on complex aftertreatment systems to reduce harmful emissions and comply with environmental regulations. At Willy Heavy Equipment & Auto Repair Inc., we understand the importance of having a repair shop you can count on for EGR and DPF repair in Calgary, AB.
About Our EGR & DPF Repair Services
EGR and DPF problems can reduce engine performance, trigger warning lights, and cause repeated regeneration issues. Our team provides EGR and DPF repair at our Calgary shop, with a dedicated service bay for diagnostics, cleaning, maintenance, and more involved aftertreatment repairs.
Mobile EGR and DPF service is also available when a truck cannot easily be brought to the shop. Our technicians can inspect many aftertreatment problems on-site and determine whether the repair can be completed in the field or requires in-shop equipment.
EGR, DPF & Aftertreatment Repair Services
Our Calgary shop supports diesel trucks and commercial vehicles with EGR, DPF, and related aftertreatment problems. Service can include diagnostics, cleaning, regeneration support, component repair, and replacement when required.
EGR and DPF services can include:
- EGR Valve Diagnosis & Repair: Inspect the EGR valve and related controls when reduced power, rough operation, or fault codes point to an EGR problem.
- EGR Cooler Repair: Check the EGR cooler for restriction, leaks, or other faults that can affect exhaust gas recirculation and engine performance.
- DPF Cleaning: Remove soot and contamination from the DPF when restriction is affecting exhaust flow or regeneration performance.
- Forced Regeneration: Perform an appropriate regeneration procedure when soot loading is elevated and the system is able to complete a controlled regen.
- DPF Replacement: Replace a damaged or failed DPF when cleaning or regeneration can no longer restore proper function.
- Aftertreatment Diagnostics: Use fault codes and system testing to identify problems involving sensors, EGR components, DPF restriction, and related emissions controls.
- Aftertreatment Maintenance: Inspect applicable components and address developing issues before they lead to repeated derates or regeneration problems.
Signs Your EGR or DPF System May Need Repair
Aftertreatment problems often affect engine power, regeneration frequency, exhaust flow, and warning light activity. These signs matter because continued operation can increase soot loading, worsen restrictions, and eventually lead to derates or more extensive emissions-system repairs.
Common signs include:
- Frequent Regeneration: Repeated regens can indicate excessive soot loading, incomplete regeneration, sensor problems, or another issue affecting DPF operation.
- Loss of Engine Power: Reduced acceleration or pulling power can develop when exhaust restriction, EGR faults, or aftertreatment problems interfere with normal engine operation.
- DPF or Check Engine Warning Lights: Warning lights may point to soot loading, pressure sensor faults, temperature issues, or other aftertreatment problems that need diagnosis.
- Rough Idle or Hesitation: Uneven operation can indicate an EGR valve that is sticking, airflow problems, or another issue affecting combustion and exhaust recirculation.
- Increased Fuel Consumption: EGR or DPF faults can affect engine efficiency, especially when the truck is regenerating more often than normal.
- Excessive Exhaust Smoke: Changes in exhaust output can indicate combustion, EGR, fuel, turbocharger, or aftertreatment problems that require inspection.
- Engine Derate: Reduced engine output can occur when the emissions system detects a fault serious enough to limit vehicle performance.
Why Calgary Trusts Us for EGR & DPF Repair
Our Calgary repair bay gives technicians the space and equipment needed for detailed aftertreatment diagnostics, DPF service, EGR repair, and more involved emissions-system work. Shop service is especially useful when the problem requires extended testing, cleaning, or component removal.
Mobile diagnostics and repair remain available for trucks experiencing EGR or DPF problems in the field. This gives customers access to both in-shop and on-site service based on the fault, vehicle condition, and repair requirements.

Frequently Asked Questions
How Do You Get to Our Diesel Repair Shop in Calgary for EGR & DPF Repair?
Our shop is located at 7350 108 Ave SE Unit 110, Calgary, AB T2C 5C8. Drivers can reach the area using Stoney Trail/Highway 201 or Deerfoot Trail/Highway 2, with 52 Street SE providing a major local route toward the shop.
The shop is beside Goodleaf Farms Calgary. Chevron and Esso gas stations are also a few minutes away along 52 Street SE, helping drivers identify the surrounding area.
How Do You Fix a Diesel Truck That Keeps Needing DPF Regeneration?
Technicians check soot loading, differential pressure readings, temperature sensors, fault codes, and related engine conditions to determine why regeneration keeps returning. Repairs may involve cleaning the DPF, replacing a failed sensor, correcting an engine or fuel problem, or repairing another fault that is causing excessive soot buildup.
What Is the Best Way to Unclog a DPF?
There are various methods for DPF cleaning, and the best approach depends on the severity of the clog. Our experienced technicians can assess your DPF and recommend the most effective cleaning method, whether it's manual cleaning, forced regeneration, or a combination of techniques.
How Do You Fix an EGR Valve That Is Causing Rough Idle or Poor Acceleration?
Technicians inspect EGR operation, related sensors, airflow, fault codes, and the condition of the valve and cooler. Repairs may involve cleaning or replacing the EGR valve, repairing the cooler, correcting sensor faults, or addressing another issue affecting exhaust gas recirculation.
How Do You Fix a Diesel Truck That Goes Into Derate Because of an EGR or DPF Fault?
Technicians scan the engine and aftertreatment system for active faults, then test the affected sensors, DPF restriction, EGR operation, and related components. Once the cause is confirmed, repairs may include cleaning the DPF, replacing failed sensors, repairing EGR components, or correcting the underlying engine condition that triggered the derate.
What Does a Bad EGR Sound Like?
A faulty EGR valve may not always cause a distinct sound. However, symptoms like rough idling, hesitation during acceleration, and black smoke from the exhaust can indicate EGR valve problems. If you have a problem with your EGR system, give us a call at 403-863-9001 or 403-218-9308!
