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.

Everything went well. Everything was done in a timely manner. Excellent customer service. Melissa kept me updated with everything that was going on.
Had to get some welding and fab work done on my car hualer trailer and Dakota there did top notch job and got it done in a timely manner looks & works like new
I'm very satisfied with the work done on F250 brake system here. My brakes were a disaster, and since I was traveling through Denver with my slide-in camper in the bed, I had to take it to a semi shop. These guys did a timely and thorough repair job, and were kind to work on my truck even though it's not a "big truck". The price was good and I will 100% be back should the occasion arise. On top of being skilled & professional, they were also friendly and easy to work with.
Although I live in NC, I've been using Schroeder Truck Repair for over 16 years. Their mechanics and people are top notch. There's not a better mechanic in the country than David. From light mechanical to big mechanical jobs to welding, Schroeder has taken care of it all for me. They're a big reason my 2016 car hauler (truck and trailer) have over 1.2 million miles and is still going strong. When I leave Schroeder I know any problem is resolved... every time. Thanks Schroeder!
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.
Did great work replacing the glow plugs, harnesses, rellay on my skoolie. They don’t always work on international but I knew what I wanted done and they were happy to oblige. Everyone there was welcoming and friendly. And a solid rate for Denver. Would definitely return
