Mobile EGR & DPF Repair Services in Bakersfield, CA

Truck Aftertreatment Repair

Modern diesel engines come equipped with sophisticated emissions systems. While they’re vital for meeting environmental standards, they can also be a source of headaches when they malfunction. That’s where we come in. Our mobile-only service ensures truck aftertreatment repair is brought straight to your location—whether you're stuck on the roadside or parked at a rest stop.

The two main culprits of emission issues? Your Exhaust Gas Recirculation (EGR) system and your Diesel Particulate Filter (DPF). Over time, carbon and soot build up in the EGR valve and cooler, clogging the flow and causing decreased performance. You'll notice rough idling, decreased fuel economy, and engine fault codes.

Your DPF is no different. If your truck can’t complete a regen, you're at risk for a power derate or shutdown. We offer DPF cleaning for trucks and can perform both passive and forced regeneration—on-site. No shop visits, no downtime.

From EGR valve replacement for trucks to soot removal, our expert care ensures your engine runs clean and meets all emission standards.

What Happens If You Don’t Fix EGR?

Neglecting a failing EGR system can cause serious consequences for your engine. When the valve is clogged or stuck, your engine runs hotter, emits more pollutants, and may experience reduced performance. Over time, these conditions can lead to further engine component damage and trigger costly repairs if not addressed early.

Can You Clean Or Repair An EGR Valve?

Yes, an EGR valve can sometimes be cleaned if buildup isn’t too severe. This involves removing the valve and clearing out carbon deposits that restrict flow. However, if the valve is damaged, corroded, or the issue persists after cleaning, a complete replacement may be the only way to ensure proper function.
