EGR & DPF Cleaning & Repair

Most diesel vehicles often experience issues in their exhaust gas recirculation (EGR) and diesel particulate filter (DPF) system. Their jobs are to reduce carbon emissions, but if they're not in optimal working condition, a faulty EGR and DPF system can end up putting unnecessary load on your engine.

Like the EGR, the diesel particulate filter (DPF) serves a similar purpose by trapping soot from the exhaust in its honeycomb-shaped exhaust pipe, storing it, and then burning it off. This also reduces carbon emissions.

These two systems are necessary for the proper operation of your truck but can run into problems if they are not serviced regularly.

DPF Cleaning & Maintenance

The diesel particulate filter (DPF) is an exhaust after-treatment device that traps particulate matter such as soot and ash. Your DPF system should be cleaned every 200,000 miles to avoid problems.

If these issues are ignored for too long, your engine may start acting up. A clear indication of this is when the dreaded yellow REGEN light appears on your dashboard.

EGR Maintenance

EGR coolers have two failure modes: plugging with soot, which restricts the flow of the gasses through the system, and fractures inside the cooler from thermal cycling and the constant pressure applied to the system.

It is vital to get your EGR system checked for any malfunctions to avoid further complications in your engine. Also, make sure to take your vehicle to a professional for timely EGR cleaning and EGR replacement if necessary.

I drive hot shot and had a situation where all my clearance lights went out. I called early in the morning and they got me in same day and had the problem fixed next day. It was a completely unreasonable ask as it was an electrical issue that I needed done in a 2 day window, not to mention they were slammed. These guys went above and beyond for me without a fuss and communicated every step of the way.  I HIGHLY recommend them to anyone. Thank you guys for all your help!

Absolutely the best customer service. I went in seeking a hard to find item that I did not want to have to wait for from amazon. To my surprise they had what I needed and made my day that much easier for my trailer repair.

We are so thankful that our motorhome was towed to JE-CO. After a very disappointing breakdown, JE-CO has been so accommodating and helpful. They have easy access, long business hours and have worked well with Ford and Tiffin to try to get our rig repaired . We would highly recommend them.Also, thank you G for keeping us informed on what’s going on.
