Forced Regen Services for Diesel Trucks in Belmont, NH

When your diesel truck throws a DPF warning light or enters derate mode, Tri-State Diesel Repair provides expert forced regen services right here in Belmont, NH. Our certified diesel techs use advanced diagnostic tools to initiate and monitor forced regeneration for your diesel particulate filter (DPF), restoring engine power and performance without unnecessary downtime.

Diesel engines equipped with emission systems need periodic regeneration to burn off soot in the DPF. When a passive or active regen fails or is interrupted, a forced regeneration becomes essential. We perform on-site forced regens using OEM software, helping your truck get back to full power—whether you're parked at your terminal or broken down roadside. Our team can also diagnose underlying issues causing regen failures, from sensors to EGR and DEF system faults.
