Nissan NP300 DPF Replacement Parts

The DPF is built around the engine and its emissions calibration, so the engine code is the most important thing to match — your breaker will need it to source the right unit. You'll find the engine code on your V5C or by asking a dealer to check against your registration. Don't rely on year alone, as the same model year could carry different engines depending on spec and market. Always confirm the engine code with the breaker before they pull the part.

The NP300 Navara (D23 generation, launched in the UK around 2016) moved through Euro 5 and Euro 6 emissions standards during its production run, and DPFs are calibrated to the emissions era of the engine they serve. A unit from the wrong emissions generation may not physically interchange or could cause the vehicle to fail MOT even if it bolts on. Name the boundary confidently: parts sourced from pre-Euro 6 vehicles should not be assumed to cross into Euro 6 applications without verification. Confirm with your breaker whether the specific unit they have matches your registration's emissions standard.

Both years sit within the D23-generation NP300 Navara, but emissions compliance updates mean a 2017 unit and a 2019 unit may not be from the same emissions era, and DPF specification can differ accordingly. Whether a part sourced from a 2017 vehicle will cross into a 2019 application is strong confirm-with-breaker territory — name your registration to the breaker so they can check the exact engine code and emissions certification. Do not assume fitment based on generation alone.

Trim level — whether Acenta, N-Connecta, Tekna, or any other — does not affect DPF fitment on the NP300; what matters is the engine code and emissions standard, which are the same across trims sharing the same drivetrain. You may find cosmetic differences around the exhaust area depending on spec, but the DPF itself is not trim-dependent. Confirm the engine code with your breaker regardless of trim, and they'll be able to match the correct unit to your vehicle.

In the UK, the NP300 Navara is the D23-generation model sold from around 2016, so 'NP300' and 'Navara' refer to the same vehicle in this market — earlier Navaras (the D40, sold roughly 2005–2015) are a different generation entirely and their DPFs will not be a straightforward swap. Even within the D23 generation, whether a specific used DPF unit interchanges is something to confirm with your breaker against your registration and engine code. Do not assume parts from the D40-generation Navara will fit an NP300.

A used DPF from a breaker can be a cost-effective option, but you should ask the breaker how many miles are on the unit and whether it has been checked for cracks, blockages, or damage — a failed DPF from a vehicle written off due to a fault may have been the cause of that fault. Ask for the donor vehicle's registration so you or the breaker can confirm the engine code and emissions standard match yours exactly. A reputable breaker will be transparent about the unit's condition, but fitment and function can never be guaranteed on a used emissions component.
