Truck EGR & DPF Repair Services in Raleigh, NC

EGR and DPF System Repair in Raleigh, NC

Here's the thing: your business relies on your truck's performance. And having to stop or delay operations is never a pleasant experience. That's why staying ahead of maintenance, especially for your after-treatment systems, is critical. When your truck starts flashing warning signs —such as reduced engine power, excessive exhaust, and a lit-up dash — there's a chance it's due to issues with the exhaust gas recirculation (EGR) and diesel particle filter (DPF) systems.  In diesel trucks, these systems are crucial for optimal performance, improved fuel efficiency, and compliance with emissions standards. When your EGR/DPF system isn't functioning properly, your truck and your business feel the impact.

Triangle Fleet Services assesses, diagnoses, and keeps your after-treatment system in top-performing shape, which is our job. We understand the ins and outs of the EGR and DPF and can keep them running as they should. It's not only critical for the environment, but also for your vehicle's performance.

What happens when your EGR stops working?

When the EGR fails, exhaust gases can't recirculate properly, causing increased NOx emissions, rough idling, poor fuel efficiency, and possible engine knocking. It may also trigger a fault code or put the engine into limp mode to prevent damage.

What is DPF failure?

DPF failure happens when the diesel particulate filter becomes excessively clogged or damaged. This prevents proper exhaust flow, leading to loss of power, increased fuel consumption, frequent regens, and potential engine derating or shutdown to protect system components.

I'm having trouble with regens on my DPF What does that mean?

Trouble with regens means your DPF isn't burning off soot as designed. Causes may include sensor faults, poor fuel quality, or short trips. If not resolved, soot builds up, restricting exhaust flow and triggering fault codes or engine derate.

Can I drive with an insufficient EGR?

Driving with an insufficient EGR is possible in the short term, but not advised. It increases engine temperatures and emissions, reduces fuel efficiency, and risks damage to the DPF and turbocharger. It may also trigger limp mode, significantly reducing engine power.
