EGR & DPF Repairin Ontario, CA.

A DPF warning light, frequent regenerations, loss of power, derate, higher fuel use and a soot level message on the dash are common signs. Short trips and lots of idling make clogging more likely.

A forced (parked) regeneration uses a scan tool to command the engine to heat the DPF and burn off soot when normal regenerations have not finished. If the filter is loaded with ash, it needs to be cleaned or replaced instead.

No. Removing or disabling emissions equipment is illegal under federal and California law. We repair and maintain these systems so your truck runs well and stays compliant.

Bad NOx sensors, poor DEF quality, a failing DEF pump or doser, and a worn SCR catalyst are common causes. We test the system to find which part is at fault.

We work on light, medium and heavy duty diesel trucks, fleet vehicles, trailers and RVs, including Freightliner, International, Peterbilt, Kenworth, Volvo, Mack, Hino, Isuzu, Ford Power Stroke, Ram Cummins and GM Duramax.

It depends on the truck, the parts and what we find. We diagnose first, then explain the repair options and the price before any work begins, so there are no surprises. Call, text or use the form to get started.

Calling ahead is best so we can plan bay time and parts. If your truck is down, call (909) 701-8755 and we will tell you the fastest way to get it in.
