DPF Cleaning vs Replacement: What’s the Real Cost?

🔥 What Does a DPF Actually Do?

DPFs capture and burn off soot particles during regeneration cycles. Over time, they clog, reducing engine power and fuel efficiency

⚠️ How Do You Know It's Blocked?

Watch for these signs:

• Loss of power or sluggish acceleration
  
  

• Decreased fuel efficiency
  
  

• Dashboard warning lights
  
  

• Failed or incomplete regeneration
  
  

• Excessive smoke
  
  

• Hard starting or rough idle
  
  

🔧 Option 1: DPF Replacement

• Cost: NZ$4,000–NZ$8,000 for new units
  
  

• Pro: Instantly clears blockage.
  
  

• Con: Very expensive and doesn’t prevent future clogging.
  
  

🧼 Option 2: DPF Cleaning

• Cost: Approximately starting from NZ$395 for passenger vehicles and utes & heavy diesel.
  
  

• Turnaround: 1–2 days typical (removal, clean, reinstall)
  
  

• Pro: Restores flow to ~98%+ OEM levels and often same-day service.
  
  

• Con: Heavily damaged DPFs may still require replacement.
