Second Hand Nissan NV400 Fuel Injector

The NV400 is exclusively diesel-powered in the UK market, and diesel engines do use fuel injectors — specifically high-pressure common rail injectors that deliver fuel directly into each cylinder. So yes, fuel injectors are a genuine part on the NV400, and used ones are regularly available from breakers. Because diesel injectors are precision components, the engine code is the single most important detail you need before sourcing one.

The NV400 was introduced in 2011 and received a significant facelift around 2014, with the model continuing into the early 2020s — so a 2014 and a 2019 van sit either side of or within a generation boundary that can bring engine and injector specification changes. The engine code, which you'll find on your V5 or via a VIN check, is the definitive factor here rather than the year alone. Name the boundary confidently to the breaker and ask them to cross-reference the engine code from the donor vehicle against yours before purchase.

The fuel injectors on the NV400 are tied to the engine, not the gearbox, so whether your van is a manual or automatic does not change which injector you need. What matters is the engine code, the engine displacement, and the power output variant, as different power outputs of the same engine family can use different injector specifications. Always quote your engine code to the breaker rather than just the gearbox type.

Trim level does not affect fuel injector fitment on the NV400 — an SE and a Tekna with the same engine code will use the same injector. Trim differences on the NV400 relate to cab comfort features, load area lining, and similar equipment rather than anything that changes the engine specification. Focus entirely on matching the engine code and power output when sourcing from a breaker.

Technically a single injector can be fitted, but diesel common rail injectors are calibrated to very fine tolerances, and mixing a used injector of unknown history with existing units can affect fuelling balance across the cylinders. This is less a fitment question and more a calibration and coding one — confirm with the breaker and your fitting garage whether the replacement injector will need to be coded or flow-matched to your engine's ECU, as this varies by engine variant and is something we cannot state as fact here.

Body style has no bearing on fuel injector fitment whatsoever — the injectors are part of the engine assembly and are identical across panel van, crew cab, and chassis cab variants that share the same engine code. When talking to a breaker, the body style of the donor vehicle is irrelevant; what you need to confirm is that the donor's engine code and power output match your own. Stick to the engine code and let the breaker do the cross-referencing.
