Diesel Particulate Filter (DPF) Regeneration

The diesel particulate filter (DPF) traps the soot produced by your diesel engine. When it fills up, the truck may show a warning light, lose power or go into derate mode. A regeneration burns off the soot and gets your truck back on the road.

  • Code reading and electronic diagnostics
  • On-site forced regeneration
  • DPF or check engine light on
  • Loss of power or derate mode
  • Finding the cause of repeated clogging
  • Mobile service or at our shop

Why diagnose first?

A DPF that clogs often can be a sign of another problem. Our mechanic checks the cause before running the regeneration, so the problem does not come back a few days later.
