Aftertreatment Repair in Darlington, SC
Our technicians begin with a full emissions system scan, checking for clogged filters, faulty sensors, or EGR valve issues. We also perform manual or forced regeneration when needed and ensure proper DEF levels and dosing. If a component is beyond cleaning, we can replace it with emissions-compliant parts.
Common EGR and DPF repairs include:
- EGR valve cleaning or replacement
- DPF inspection, cleaning, or regeneration
- DEF system repair and refilling
- Sensor and harness diagnostics
- Full aftertreatment system overhauls
We also monitor backpressure, soot levels, and temperature differentials across the filter to ensure full system recovery. These emissions components are essential—not only for legal compliance but also for your truck’s performance.

What Is the Purpose of a DPF?
The Diesel Particulate Filter traps soot and carbon particles from exhaust gases, preventing them from entering the atmosphere. It must be cleaned regularly to prevent backpressure and performance issues.
How Do I Know If My EGR Valve Is Bad?
