Aftertreatment is what puts modern diesels on the side of the road. We do forced regens, DPF cleaning, DEF system repair and the diagnostic work behind them — in our West Palm Beach shop or at your yard.
When a truck will not regen on its own and drops into a derate, we run a forced regen and then find out why it got there — because a regen alone is a symptom fix.
Diesel particulate filter removal, cleaning and reinstallation, with the inlet and outlet pressures checked after, so you know the filter actually came clean.
DEF pumps, injectors, lines, heaters, quality and level sensors, and the SCR faults that turn into a 5 mph derate if they are ignored.
NOx sensors, differential pressure sensors, temperature sensors and the wiring behind them — the parts most often replaced when the real fault was a connector.
EGR valves, coolers and related cooling-system work, including the coolant loss that gets blamed on a head gasket.
Full electronic diagnosis: stored and active codes, live data, and a plain-English explanation of what the truck is telling us and what it will cost.
We pull codes and live data and confirm the actual fault instead of replacing the part the code is named after.
You get the number before work starts, with the option explained: clean it, repair it, or in some cases replace it.
We re-check pressures and sensor data after the repair so the truck leaves clean, not just code-cleared.
Short runs and stop-and-go delivery routes are the worst case for a diesel particulate filter. The truck never gets hot enough or long enough to complete a passive regen, soot builds, the active regens get more frequent, and eventually the filter plugs and the engine derates — usually on the worst possible morning.
The fix is not just cleaning the filter. It is knowing which trucks in your fleet run short routes and getting ahead of them on a schedule. That is exactly what the inspections in Fleet Care are for.
