2004 Nissan Navara 2.4L Diesel · PX54 HSY

The 2004 Nissan Navara presents a mixed maintenance picture. The most recent MOT, conducted on 4 May 2022 at 158,198 miles, passed, but the record reveals a vehicle that has been managed with a light touch rather than proactively repaired. The trend is one of stable but persistent minor faults rather than a clear improvement or a rapid decline. Recurring advisories for oil leaks and structural corrosion suggest long-term issues that have been monitored rather than rectified. The gap between the last test and today, over four years without a current certificate, is a significant concern that overshadows the historical data. The mileage accumulation is remarkably low and suspiciously flat. Between the 2021 test at 150,978 miles and the 2022 test at 158,198 miles, the vehicle covered 7,220 miles in a year. However, the recorded mileage has remained at 158,198 miles since that May 2022 test. This indicates the vehicle has either been standing unused for over four years or the mileage is no longer being accurately recorded. A 22-year-old vehicle with this final reading has averaged roughly 7,191 miles per year, which is typical for its age, but the recent static mileage points to prolonged inactivity, which carries its own risks for seized brakes, perished rubber components, and fuel system degradation. A buyer must approach this Navara with a thorough mechanical inspection, focusing on the areas repeatedly flagged in its history. The suspension requires close attention. The 2019 failure for excessively worn anti-roll bar bushes on both sides was downgraded to advisories in subsequent tests, implying the components were left to deteriorate. The prop shaft bearing, noted for slight play in both 2019 tests, should be checked for any progression into a vibration or clunk under load. The braking system is another critical area. The 2020 advisory for corroded rear brake back plates and worn front discs, combined with the risk of a vehicle standing for years, means a full brake strip-down is essential to check for seized calipers, binding handbrake mechanisms, and corroded hydraulic lines. The structural integrity of the chassis and body mounts demands a rigorous inspection. The 2022 test flagged corrosion within 30cm of a mounting point, and the 2019 tests noted general structural corrosion. On a Navara of this age, this is a critical pass/fail item that can worsen rapidly if left untreated. The persistent oil leak advisory, present in 2021 and 2022, should be traced to its source, whether a rocker cover gasket, oil cooler pipe, or crankshaft seal, to assess if it has become a more serious seep during its period of inactivity. Finally, the tyre condition must be verified. A nail was found in the offside rear in 2022, and tyres that have been stationary for four years will almost certainly have flat-spotted, perished, or cracked sidewalls, making them unsafe regardless of remaining tread depth.
