Seeing power loss, frequent regens, or warning lights? This page breaks down EGR and DPF repair, what causes failures, and how our mobile team gets you rolling again—on your schedule, at your location.
Mobile Aftertreatment Repair
When soot builds or sensors drift, performance drops and derate risk rises. We start with full-system diagnostics—scan data, differential pressure, inlet/outlet temps, and leak checks—so we fix causes, not just clear codes. Our process verifies EGR system health with command tests, flow checks, and cooler inspection. If components are seized or worn, we handle valve replacement and sealing surfaces on-site. We also evaluate DEF levels, inspect for crystallization, and troubleshoot malfunctions so failed dosing doesn’t masquerade as a DPF issue. If lines or injectors are broken, we replace and re-test.
For soot control, we perform dpf repair and maintenance to restore backpressure and stabilize regen frequency. Where contamination is severe, we provide dpf cleaning or removal for off-unit thermal service, then reset adaptives and road-test.
What Makes Us Different
You choose the place and time—yard, job site, or roadside—and we show up ready to diagnose and repair. Because we’re fully mobile, you avoid towing, waiting rooms, and moving equipment off-route. Any make or model is welcome; mixed platforms aren’t a problem, so one call covers your entire lineup.

Communication stays clear from start to finish. You’ll get findings in plain language, options that respect your timeline, and upfront pricing. Repairs happen on-site whenever possible—from sensor replacements to EGR service to DPF cleaning—and we validate the fix with data, resets, and a confirmation drive. The result is a reliable solution without the disruptions that come with traditional shop visits.

What Is An EGR System?
An EGR system routes a metered amount of exhaust back into the intake to lower combustion temperatures and reduce NOx emissions. It includes a valve, cooler, passages, and sensors. Proper flow is critical; carbon buildup, sticking mechanisms, or cooler restrictions can trigger drivability issues and fault codes.
Is It OK To Drive With A Bad EGR System?
Driving with a faulty EGR can lead to rough running, increased emissions, and potential DPF overload from poor combustion. Continued operation may force frequent regens or even a derate. It’s best to diagnose promptly to prevent collateral failures and restore normal engine and aftertreatment function.
