DPF
Specialized cleaning and restoration for Diesel Particulate Filters to ensure optimal airflow.
SCR
Technical diagnostics and efficiency testing for selective catalytic reduction hardware.
EGR
Maintenance protocols for exhaust gas recirculation valves to prevent manifold carbon buildup.
DOC
Inspection and testing of diesel oxidation catalysts to maintain critical oxidation performance.
DEF
Comprehensive care for Diesel Exhaust Fluid tanks, pumps, and specialized dosing injectors.
Systems We Diagnose

- Regeneration-related faults
Truck in Derate or Having Regen Problems?
Facing failed or frequent regenerations, DPF warning lights, DEF warnings, SCR faults, NOx sensor faults, check-engine lights, or loss of power and derate?
A fault code does not always mean the named component needs replacement. Proper diagnostics identify underlying sensor, wiring, engine, or exhaust issues before parts are replaced unnecessarily. We find the root cause of aftertreatment errors to save you time and money on major hardware.
