Signs Your Diesel Service Needs Service
DPF Regen Warnings
Frequent forced regens or a clogged-filter light mean the particulate filter needs cleaning or service before it derates you.
DEF / SCR Faults
DEF-quality or SCR codes, a flashing emissions lamp, or a countdown-to-derate warning need diagnosis fast.
EGR Codes
EGR valve or cooler faults cause rough running, poor economy, and check-engine lights we can trace and repair.
Poor Fuel Economy
A sudden MPG drop often points to fueling, sensors, or a restricted exhaust aftertreatment system.
Derate or Limp Mode
A speed-limited derate is the truck protecting itself — get the underlying emissions fault read before the next step.
Failed Emissions Test
We diagnose and repair the root cause so your truck passes and stays compliant with FMCSA and Nebraska requirements.

Common Diesel Service Questions
My truck is in a DEF derate — can you help fast?
Yes. A DEF or SCR derate is time-sensitive because the speed limit drops further over time. Bring it in or call our 24/7 roadside line in Lincoln and we will read the fault and get you running.
Can you clean or replace my DPF?
Both. We perform forced regens, bake-and-clean DPF service, and full filter replacement depending on the soot and ash load, then verify the aftertreatment system is back in spec.
Do you delete emissions systems?
No — emissions deletes are illegal on road-going trucks and risk heavy fines and CSA penalties. We repair DEF, DPF, and EGR systems to keep you legal and out of derate.
Will fixing emissions faults improve my fuel economy?
Often, yes. A clogged DPF, stuck EGR, or failing sensor makes the engine work harder. Restoring the aftertreatment system to spec frequently recovers lost MPG.
Do you service all truck makes?
Yes — Cummins, CAT, Detroit, and PACCAR MX emissions systems across all major Class 6–8 makes at our Lincoln, NE shop.
