Heavy-Duty Aftertreatment Repair In Converse, TX, Just Outside San Antonio
Modern diesel trucks rely on advanced aftertreatment systems to stay compliant with emissions regulations. When these systems fail, downtime can disrupt your schedule and cost you money. That’s why we provide reliable truck aftertreatment repair, addressing both the EGR system and DPF system.
Some of the most common issues include clogged filters, faulty sensors, and EGR system malfunction for trucks. A blocked DPF can cause reduced power, higher fuel use, and frequent regenerations, while a failing EGR valve may lead to rough idling, poor fuel economy, or check engine lights.
Our technicians handle everything from DPF cleaning for trucks and forced regeneration to complete part replacements. We also offer thorough soot removal to ensure your truck runs cleaner and more efficiently, whether you’re operating locally in Converse or managing fleet operations across San Antonio.

Addressing EGR issues early helps prevent costly repairs and keeps your truck performing efficiently in areas like San Antonio where consistent uptime matters.
How Do You Tell If A DPF Is Clogged?
A clogged DPF often shows up as dashboard warning lights, reduced engine performance, and increased fuel consumption.
