2021 Nissan NV400 Tekna DCI Auto 2.3L Diesel · SN71 AZG

The most recent MOT test on 2025-10-14 resulted in a failure, with the vehicle retaining a single passing grade from 2024-09-11, indicating a concerning maintenance trend. The repeated advisory regarding the front brake discs—described as worn, pitted, or scored but not seriously weakened—suggests a persistent issue that has not been resolved or adequately addressed. This recurring defect is critical, as worn brake discs, particularly when pitted, can lead to reduced braking performance, increased stopping distances, and potential failure under heavy loads or emergency braking. The presence of passing faults related to headlamp alignment and beam projection, while not directly mechanical, further highlights a lack of proper attention to optical and lighting systems, which can compromise road safety. The failure to rectify these issues between tests raises questions about the vehicle’s upkeep and whether the owner has prioritised corrective maintenance over minor cosmetic or functional adjustments. The recorded mileage of 79,580 miles for a 2021 Nissan NV400 is exceptionally high for its age, averaging approximately 15,916 miles per year—a rate that far exceeds the typical usage of most vehicles in the UK. Such high mileage typically correlates with increased wear on consumables such as brake pads, suspension components, and drivetrain elements, as well as potential stress on the engine, transmission, and exhaust system. The absence of a clear maintenance service history or mileage gaps suggests either aggressive driving habits, frequent long-distance travel, or a combination of both. This level of usage can accelerate the deterioration of suspension bushes, coil springs, and steering components, leading to premature failure or reduced handling stability. Additionally, high-mileage vehicles are more susceptible to issues such as drivetrain wear, transmission fluid degradation, and potential oil dilution in diesel engines, particularly if the vehicle has been driven in extreme conditions or without regular servicing. Given the recurring MOT advisories and high mileage, the prospective buyer must prioritise a thorough mechanical inspection to assess the severity and extent of the brake disc wear, which could require replacement if the discs are beyond a safe operational threshold. The pitted or scored condition of the discs may also indicate underlying wear on the brake pads or rotor cooling, necessitating a check for pad thickness, heat warping, and potential caliper binding. During a test drive, listen for unusual noises such as grinding, squeaking, or vibration during braking, which could signal impending failure. Additionally, inspect the front brake system for uneven wear patterns on the discs or pads, which may point to misalignment or excessive heat buildup. The offside and nearside headlamp alignment faults should be corrected immediately, as improper beam projection can impair visibility and increase the risk of accidents. Addressing these issues promptly will improve both roadworthiness and safety. Beyond the immediate concerns, the buyer should also conduct a comprehensive inspection of the vehicle’s suspension, focusing on the front and rear suspension components. Given the high mileage, check for signs of excessive play or binding in the control arms, struts, and shock absorbers, as well as the condition of the suspension bushes, which may show signs of cracking or excessive wear. Listen for clunking noises when driving over bumps or uneven surfaces, which could indicate failing suspension elements. The drivetrain and exhaust system should also be examined for signs of wear or leaks, particularly around the driveshaft, universal joints, and exhaust manifold. Given the vehicle’s age, consider checking the tyre tread depth and sidewall condition for signs of perishing or cracking, which can compromise tyre integrity and safety. Furthermore, verify the health of the 12V battery and starter motor, as high mileage can accelerate battery degradation, especially if the vehicle has been left unused for extended periods. Finally, ensure that all fluids—oil, coolant, brake fluid, and transmission fluid—are at the correct levels and show no signs of contamination or degradation, as these can affect engine longevity and drivetrain performance. If possible, obtain a detailed service history to confirm that routine maintenance such as oil changes and fluid top-ups have been carried out according to Nissan’s recommended intervals.
