Ignoring aftertreatment system maintenance can lead to expensive repairs, fines, and vehicle downtime. Here are some common signs that indicate your DPF, SCR, or EGR system may need servicing:

• Reduced Engine Power – A clogged DPF or faulty SCR system can limit performance.
• Increased Fuel Consumption – A failing aftertreatment system forces your engine to work harder.
• Check Engine or Emissions Light – Faulty sensors or system errors trigger warning lights.
• Excessive Regeneration Cycles – Frequent regen cycles may indicate DPF clogging.
• Strange Exhaust Smell or Smoke – Malfunctioning systems can produce excessive smoke or odors.

If you notice any of these issues, it’s time to schedule an aftertreatment system inspection at Ridge Equipment & Truck Repair Co.
