Used Nissan NV400 Dual Mass Flywheel

Yes, the NV400 can be fitted with a dual mass flywheel (DMF) on its diesel variants, which cover all mainstream engine options in this van — primarily the 2.3-litre dCi unit badged under the Renault/Nissan alliance. DMFs are used on manual gearbox versions to smooth out the inherent vibration of the diesel engine, so if your NV400 has a manual transmission, it is very likely to have a DMF rather than a solid flywheel. If you are unsure, your engine code (found on the V5 or a VIN check) will confirm the exact unit fitted.

The NV400 launched in the UK in 2011 and received a facelift around 2014-2015, with the model continuing into the early 2020s — so a 2014 and a 2019 vehicle sit either side of or around that facelift boundary, which can bring changes to ancillary components. The DMF itself is primarily determined by the engine code rather than the model year, so if both vans share the same engine code the core flywheel may be compatible, but you should confirm this directly with the breaker against both registration numbers before buying.

Trim level makes no difference to dual mass flywheel fitment — the DMF is entirely engine and gearbox-driven, not trim-driven, so an SE, Sport, or any other grade will use the same flywheel if the engine code and gearbox type match. The trims differ in comfort and convenience features rather than drivetrain components, so when quoting your enquiry to a breaker you only need to supply the engine code, fuel type, and whether the van is manual — not the trim name.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker exactly which flywheel variant was originally fitted. You should also confirm it is a diesel and that the van has a manual gearbox, as automatic versions use a torque converter rather than a flywheel. Body style, wheelbase length, and roof height make no difference to flywheel fitment and do not need to be included.

The NV400 is built on a shared platform with the Renault Master and Vauxhall Movano, and all three use the same Renault-sourced 2.3-litre dCi engine family, meaning DMF parts frequently cross over between these sister vans. However, because there are multiple engine output variants (100, 125, 145, and 170 bhp versions, among others) and the flywheel specification can differ between them, you should match engine codes rather than just van badges. Tell the breaker the engine code from both vehicles and let them confirm the match rather than assuming badge equivalence guarantees compatibility.

No — automatic gearbox versions of the NV400 do not use a dual mass flywheel at all; instead they use a torque converter to transmit drive from the engine to the transmission, which serves the same vibration-damping purpose in a completely different way. If you are hearing noise or vibration on an automatic NV400, the DMF is not the component to investigate, and a breaker will be unable to supply one for that drivetrain. You should speak to a mechanic about diagnosing the actual fault, which may relate to the torque converter, drivetrain mounts, or another component.
