Heavy-Duty Truck EGR & DPF Repair in Dubuque, IA

Truck Aftertreatment Repair in Dubuque, IA

Your aftertreatment system works hard to reduce emissions—but when it fails, performance and fuel economy take a hit. If your truck is stuck in derate mode or burning too much fuel, then it could point to aftertreatment issues.

If you breach emissions regulations, then you can be fined over $45,000 per noncompliant vehicle. If you operate a large fleet, this is going to take a huge chunk out of your budget.

How Do I Know If My DPF Is Clogged?

A clogged DPF in heavy-duty diesel vehicles shows symptoms like loss of power, increased fuel consumption, warning lights, frequent regenerations, and excessive exhaust smoke. Diagnostics may reveal high backpressure or fault codes. Regular monitoring helps detect clogging before it affects engine performance or emissions compliance.

Can You Clean or Repair an EGR Valve?

Yes, an EGR valve in heavy-duty diesel vehicles can often be cleaned if clogged with carbon deposits. If cleaning doesn't restore function or if the valve is damaged or stuck, replacement may be necessary. Regular maintenance helps prevent buildup and prolong EGR system performance.
