An analysis of 1,149 real DVSA MOT tests on the Nissan Nv400 Tekna Dci — what fails, how often, and how that compares to every other car on UK roads.
Where the Nissan Nv400 Tekna Dci fails its MOT
The single biggest MOT failure point on the Nissan Nv400 Tekna Dci is light unit fault — this model is 18 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 1,149 MOT tests, 3.67% of all Nissan Nv400 Tekna Dci tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include windscreen or window damaged or seriously disco... (5.3x the fleet average) and headlight fault (5.3x the fleet average). These ratios compare the Nissan Nv400 Tekna Dci's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 2 categories: Lights & Electrics, Wipers & Windscreen. If you're inspecting a Nissan Nv400 Tekna Dci before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Nissan Nv400 Tekna Dci's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
The standout failure at this mileage is windscreen or window damaged or seriously disco... at 5.3x the fleet average.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Nissan Nv400 Tekna Dci specifically, the DVSA data shows the most common failures at this mileage are light unit fault (18x the average) and headlight fault (5.3x).
The shift from windscreen or window damaged or seriously disco... at lower mileages to light unit fault at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
