Aftertreatment Repair in Lac La Biche, AB
Aftertreatment systems like EGR and DPF are essential for reducing emissions—but when they fail, they can cause poor performance, regen issues, or even engine shutdown. We specialize in diagnosing and repairing aftertreatment systems on heavy-duty, medium-duty, and light-duty trucks. Our aftertreatment repair services include:
- DPF Cleaning and Regeneration – A clogged diesel particulate filter increases backpressure and reduces power. We clean, bake, or replace DPFs to restore optimal flow.
- EGR Valve Replacement – A malfunctioning EGR valve can lead to rough idling, poor fuel economy, and check engine lights. We replace faulty valves to restore proper air-fuel ratios.
- EGR Cooler Replacement – EGR coolers lower exhaust gas temperatures before recirculation. Cracked or leaking coolers can cause coolant loss or white smoke. We replace damaged coolers with OEM-grade units.
- Sensor Replacement and Calibration – Failed sensors—like temperature or pressure sensors—can trigger false regen cycles or cause system shutdowns. We replace and recalibrate sensors to restore system accuracy.
- Forced Regeneration and Diagnostics – If your truck won’t regenerate or is stuck in limp mode, we use dealer-level software to perform manual regens and reset system faults.

FAQs
What Are the Signs of a Bad DPF?
Common signs include poor acceleration, increased fuel consumption, frequent regen cycles, and warning lights. A clogged or failed DPF restricts exhaust flow and can lead to engine derate or shutdown.
Is It Better to Clean or Replace an EGR Valve?
Cleaning can work for mild carbon buildup, but if the valve is sticking, cracked, or failing electronically, replacement is usually the more effective and long-lasting solution.
