What you are looking at

No photograph available

We do not hold a verified photograph of the Diesel particulate filter yet. We would rather show none than show a picture of a different part.

What goes wrong

The YS23DDT 2.3-litre biturbo diesel in D23 Navaras is fitted with a diesel particulate filter that has a documented internal substrate cracking failure mode. The cracked DPF can emit ceramic fragments into the exhaust stream and, in severe cases, into the engine. This was the subject of ACCC enforcement action against Nissan Australia in 2021, resulting in a mandatory remedy program for affected owners.

What you would notice

  • DPF or engine warning light on dash
  • Fault codes for DPF differential pressure sensor
  • More frequent DPF regeneration cycles
  • Unusual exhaust smell or increased soot deposits
  • Reduced engine performance or limp mode activation

How to check it

Where to look. Exhaust system – diesel particulate filter canister mounted in the exhaust stream behind the catalytic converter

  1. Connect OBD2 scanner and check for active or stored DPF pressure fault codes.

  2. Ask the seller or a Nissan dealer to verify recall compliance status by VIN.

  3. Inspect exhaust outlet for abnormal soot.

  4. Request any dealer service history related to DPF inspection or replacement.

Parts involved: Diesel particulate filter.

What it costs to put right

$3,500 to $7,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Has the DPF been inspected or replaced under the Nissan recall or ACCC remedy?”
  • “Is there any dealer service history for DPF-related faults?”
  • “Has a DPF warning light appeared on the dash?”

Now check the Nissan Navara you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
