DPF cleaning vs replacement: what's the real cost?

In short: a new diesel particulate filter (DPF) typically costs NZ$4,000–NZ$8,000. Cleaning costs a fraction of that and restores flow through the filter you already have. Replacement is only needed when the filter is physically damaged, for example cracked or melted.
What does a DPF do?
A DPF captures soot particles from the exhaust and burns them off during regeneration cycles. Over time it clogs, which reduces engine power and fuel efficiency.
How do you know your DPF is blocked?
- Loss of power or sluggish acceleration
- Higher fuel use
- 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 a new unit
- Pro: clears the blockage immediately
- Con: very expensive, and doesn't prevent future clogging
Option 2: DPF cleaning
- Cost: a fraction of replacement. Ask us for a quote for your vehicle.
- Pro: restores flow through the filter you already have
- Con: a heavily damaged DPF may still need replacing
Which is right for you?
If the filter isn't cracked or melted, cleaning is usually the place to start. Send us your vehicle details and the symptoms and we'll tell you whether cleaning is likely to work.
