Every time the check engine light flashes, your day gets harder. Soot buildup and clogged filters slow you down, burn fuel, and risk fines. Heavy-duty and medium-duty EGR and DPF repair clears the problem so you can run cleaner and stronger.

Truck Aftertreatment Repair in Ronkonkoma, NY

Modern diesel trucks rely on advanced aftertreatment systems to reduce harmful emissions and meet regulatory standards. However, these systems—particularly the EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter)—require expert care when problems arise. Remember, breaching regulatory compliance can see you fined in excess of $45,000 per non-compliant vehicle!

If your DPF filter is clogged or your EGR valve is malfunctioning, you may notice:

  • Loss of engine power
  • Decreased fuel efficiency
  • Regeneration failures
  • Constant warning lights
  • Engine shutdowns or derate mode

We offer:

  • Truck DPF cleaning and filter diagnostics
  • EGR valve replacement for trucks
  • Soot removal and regen cycle resets
  • Full DEF system checks
  • Sensor inspections and wiring repair
  • ECM reset and code clearing post-repair

What areas do you serve for heavy-duty and medium-duty EGR and DPF repair?

We are located at 3045 Veterans Memorial Highway, Ronkonkoma, NY 11779, and proudly serve all of Suffolk County and parts of Nassau County.

How do you flush out a DPF?

To flush out a DPF (Diesel Particulate Filter) in a heavy-duty or medium-duty diesel truck, technicians use specialized DPF cleaning machines or perform forced regeneration. This removes soot and ash using high heat, air pressure, or liquid cleaning agents. Proper diagnostics ensure that cleaning is necessary and practical.

What happens when an EGR goes bad?

When an EGR (Exhaust Gas Recirculation) valve goes terribly wrong in a heavy-duty or medium-duty diesel truck, it can cause rough idling, poor fuel economy, engine knocking, loss of power, increased emissions, and potential engine damage due to improper combustion or soot buildup in the intake system.
