2017 Nissan NV400 2.3L Diesel · YA17 FHM

The defining mechanical story of this NV400 is one of escalating front-end wear, with steering and tyre issues becoming the headline concerns as the vehicle enters its eighth year of service. The most recent test on 13 May 2024 produced a pass, but only after a prior failure on the same date for a split nearside front outer CV joint boot that could no longer keep dirt out, a Major defect that should not be considered trivial given the mileage and the fact that contaminated grease within a constant velocity joint accelerates internal wear dramatically if left unattended. Alongside that, the inspection recorded play in the steering rack inner joint and flagged front tyres that were very worn on the outer sidewalls on both sides, suggesting a tracking or suspension geometry issue rather than simple age-related wear. A chipped windscreen and an inoperative nearside rear registration plate lamp were noted as Minor items, meaning they passed on the day but warrant correction. Looking at the trajectory from the clean 2022 test, through the 2023 advisories for perished and outer-edge worn tyres, and into the 2024 advisories, the pattern points to a chassis and steering assembly that is demanding close attention rather than a vehicle that has held its condition. Annual mileage on this NV400 averages roughly 19,700 miles per year, which is high for a nine-year-old commercial and reinforces that this is a working vehicle rather than one that has seen light or intermittent use. The testing history shows no multi-year lay-up, with annual MOTs recorded and mileage continuing to accumulate between tests, which is positive from a drivetrain and component longevity standpoint but does mean that consumables such as brakes, tyres, bushes, and steering components are likely to be closer to the end of their service life than they would be on a lower-mileage example. At 177,650 recorded miles, the diesel powertrain, clutch, turbo, dual-mass flywheel if fitted, and injection system are all operating well into their wear windows, and any prospective buyer should anticipate that some of these items may soon require remedial work even though none has yet been flagged on an MOT. For a buyer considering this NV400, the immediate priority is a hands-on inspection of the front suspension and steering geometry, given that outer-edge tyre wear on both sides is rarely coincidental and is more often linked to worn wishbone bushes, top mounts, or a tracking issue stemming from the play already identified in the steering rack inner joint. On a test drive, listen for clonking or knocking from the front when traversing speed bumps or rough tarmac, feel for vagueness or a wandering sensation through the steering wheel, and pay particular attention to any vibration or shunt through the front wheels under braking, as the split CV boot noted in May 2024 could have allowed accelerated wear to the joint itself. Inspect both front tyres closely for uneven shoulder wear, and verify that the steering rack has since been inspected or replaced, since inner joint play tends to worsen progressively rather than resolve itself. Beyond the steering and tyre concerns, the rest of the vehicle demands the usual diligence expected of a high-mileage diesel panel van, including a careful check for oil leaks from the engine and turbo, the condition of the clutch and gearbox for any sign of slip or worn synchros, and a thorough examination of the underside for corrosion, particularly around the rear brake pipes, subframe, and outriggers which are common MOT failure points on NV400s of this age. On the road, listen for diesel knock on cold start, watch the exhaust for blue smoke under load which would indicate turbo or piston ring wear, and confirm that the cooling system is holding pressure with no signs of weeping from the radiator or header tank. Given the recorded defects, this is a vehicle that can still be a sound working proposition, but only if the steering and front suspension work has been completed to a satisfactory standard, fresh tyres of the correct size and profile are fitted all round, and the CV joint has been properly attended to with a new boot and fresh grease.
