2006 Nissan Navara 2.5L Diesel · M123 ADK

The Nissan Navara’s most recent MOT test on 2025-05-20 confirms it passed without defects at 178,618 miles, though it was previously failed on 2025-05-16 at just four miles less. This back-to-back retest suggests a minor administrative or procedural oversight rather than a persistent mechanical issue, as no recurring faults were logged. The last full MOT cycle before this was clean in 2023 at 168,446 miles, indicating a stable pattern of passing tests with no repeated advisories or major failings. However, the absence of any recorded defects across all tests—including the two failed attempts—raises caution. A vehicle that consistently avoids failings on critical components (brakes, suspension, emissions) may still harbour hidden wear, particularly in high-mileage areas like drivetrain seals, transfer case fluid, or structural corrosion. The recorded mileage of 178,618 miles over 20 years aligns with typical usage for this model, averaging around 8,900 miles annually. The gap between the 2021 and 2023 MOTs—roughly 18,000 miles in two years—suggests no prolonged periods of inactivity, which could have allowed corrosion or fluid degradation. The rapid accumulation between 2021 (155,123 miles) and 2023 (168,446 miles) might imply heavier usage, potentially accelerating wear on components like differentials, transfer case bearings, or suspension bushes. Notably, the 2025 retest interval of just four miles between failure and pass is unusual and warrants scrutiny of whether the vehicle was driven to the test centre under load or if the failure was procedural. Given the lack of recorded defects, a buyer should prioritise an independent inspection of high-wear areas not typically caught by MOT standards. Focus on the drivetrain—check for leaks around the transfer case, differentials, and rear axle seals, as these are often overlooked until failure. The suspension should be examined for worn or cracked bushes, particularly at the rear, where binding or uneven wear is common in this model. Brake discs and calipers, though not failed in MOTs, may show uneven thickness or glazing, especially if the vehicle was driven aggressively. Structural integrity is critical; inspect the sills, wheel arches, and subframe for corrosion, as this model is prone to rust progression over 20 years. Finally, verify the condition of the exhaust system for cracks or holes, as emissions-related failures are not always logged until they become severe.
