2001 Nissan Navara 2.5L Diesel · Y672 BBC

The most recent MOT test on the 2001 Nissan Navara, conducted on 2024-02-22, resulted in a passing grade, though it included a significant advisory regarding general chassis corrosion throughout the vehicle. This follows a pattern of mixed results over the past two years, with two failed MOTs in 2022 and 2024, each highlighting persistent issues such as tyre wear approaching legal limits, exhaust leaks, and non-functional lamps. While the latest test shows an improvement in roadworthiness—with no dangerous failures—this does not entirely mitigate the underlying wear and tear concerns, particularly the corrosion advisory, which suggests long-term structural vulnerability. The advisory from 2023-01-21 on the near-side rear tyre worn close to the legal limit, alongside the repeated tyre wear advisories, indicates a pattern of excessive tread loss, which could compromise hydroplaning safety and traction, especially in wet conditions. The front exhaust leak, now classified as major in 2024, underscores the need for immediate attention to emissions compliance and potential catalytic converter damage, as exhaust leaks can also lead to carbon monoxide ingress and engine misfires. The recorded mileage of 177,729 miles for a vehicle aged approximately 25 years represents a relatively moderate annual usage rate of around 7,109 miles per year, which is typical for its age and class. This figure does not suggest excessive wear from high mileage alone, but it does imply significant exposure over time, particularly to suspension, braking, and tyre systems. The lack of dramatic mileage spikes or sudden increases suggests the vehicle may have been used intermittently, possibly due to storage periods or seasonal demand, rather than continuous high-wear operation. However, the consistent advisories on tyre wear—including multiple instances of tread approaching the legal limit—point to either underinvestment in tyre maintenance or prolonged periods of low-speed, low-traction driving, which accelerates tread degradation. The annual usage rate also raises questions about the vehicle’s operational conditions, such as whether it was frequently driven in wet or uneven terrain, which could exacerbate tyre and suspension wear. Given the MOT history, the prospective buyer should prioritise a thorough inspection of the chassis for signs of corrosion, particularly in areas prone to moisture exposure such as the underbody, wheel arches, and cross members. The repeated advisories on tyre wear close to the legal limit necessitate immediate attention; the buyer should measure tread depth across all tyres and replace any that are below 3mm, as this is the minimum safe threshold for wet-weather traction. During a test drive, listen for uneven tyre wear patterns, which may indicate misalignment, suspension issues, or improper wheel balancing. The major exhaust leak should be addressed promptly to prevent further catalytic converter damage and ensure emissions compliance, with a recommendation to have the exhaust system inspected and repaired by a qualified technician. Additionally, check for any signs of carbon buildup or exhaust backpressure, which could indicate deeper mechanical problems. Beyond the MOT findings, the buyer should conduct a comprehensive physical inspection of the vehicle’s structural integrity, focusing on the chassis for signs of rust penetration, which could compromise the vehicle’s safety and long-term reliability. Inspect the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of wear or failure, such as excessive play in the steering or clunking noises during cornering. The steering idler bush worn on the near-side front, noted in the 2023 advisory, should be replaced to prevent steering play and potential alignment issues. For the brakes, visually inspect the discs and linings for signs of warping, glazing, or excessive thickness wear, and listen for any grinding noises during braking, which could indicate metal-to-metal contact and impending disc failure. Given the vehicle’s age and the low mileage relative to its condition, it is advisable to check the tyre sidewall for signs of perishing or cracking, which can compromise tyre integrity and safety. Additionally, verify the condition of the 12V battery and starter motor, as older vehicles are more prone to electrical system failures, especially if the vehicle has been stored for extended periods. Finally, consult the service records to confirm that time-based fluid servicing, such as the oil change interval (typically every 12,000–15,000 miles or every 12 months), has been adhered to, as fluid degradation over time can lead to engine and transmission issues.
