The EGR and DPF system in your heavy-duty truck work together as part of your emissions system to limit the output of harmful exhaust.
An Exhaust Gas Recirculation (EGR) is a valve that also reduces emissions. It works by circulating part of the exhaust gas back to the engine’s cylinders. This prevents DPF failure because it sends gases away from the engine, making it run more efficiently. The main goal of an EGR is to reduce the amount of nitrous oxide running through the exhaust system.
A Diesel Particulate Filter (DPF) is a part of the exhaust of your truck that collects soot to keep the air clean. It captures particles in a mesh net and reduces harmful emissions.
Your truck’s EGR and DPF systems are essential components for proper engine emission control. Regular maintenance is important to assure correct engine function and proper emission compliance. Although they do reduce emissions, these systems often put a strain on your engine and, especially if not maintained, can reduce the lifespan of your diesel truck.
How to tell if your EGR and/or DPF systems are blocked
The EGR can become clogged and get stuck open or closed and your DPF system can quickly become clogged. Diesel trucks and their emissions control systems are designed for heavy towing at long distances. So, if you're using your diesel truck as a grocery-getter, you'll likely run into emission control system problems.
You'll know your DPF is blocked when an orange light appears on your dashboard (it will look like smoke blowing through a filter). But why wait until it’s completely clogged? When dealing with a clogged EGR or DPF, cleaning is an essential service. The service technicians at Schroeder Truck Repair are experienced in EGR and DPF repairs, maintenance and cleaning. Our technicians provide a detailed, quality cleaning and repair service for your EGR and DPF.

FAQs
What Happens If An EGR Valve Problem Is Left Unrepaired?
If an EGR valve problem is ignored, it can increase soot and NOx output, overwork the DPF and SCR system, trigger derates, and lead to a larger emissions system repair. Early diagnosis helps prevent recurring faults, excessive downtime, and unnecessary aftertreatment expenses.

I lease trailers to owner operators in the Southeast and one of my trailers happened to get stuck at Phil, Mike, and Brandon's garage Schroeder Truck Repair for several months. These guys are the absolute best, they are kind, understanding, professional, and their staff is the same. They communicated, took pictures and helped me when i know a lot of other places would not spend the time to be helpful. They are guys you can trust. I highly recommend them. My driver's who had work done there as well, also had a good experience. I would imagine they would and should have hundreds of 5 star reviews. Honest guys running a great business and doing it the right way. Thank you so much.

Great experience at a bad moment. They took our truck in their shop right after arrival, diagnosed bad batteries and lose wire on the alternator that was causing battery overcharge.They already had the right batteries, replaced them and it took them 1h45min together with diagnostics and replacement. The charge was fair as well. I wish every shop was like them. Right on point, great feedback and organized.We didnt even had to cancel our reload. We loaded on time and kept trucking. Two thumbs up!
