2017 Nissan Qashqai 1.5L Diesel · LIB 80

The most recent MOT test, conducted on 2025-10-23, resulted in a failure due to a critical engine malfunction indicated by the Malfunction Indicator Lamp (MIL), alongside advisories concerning front brake disc wear and fluctuating service brakes. This marks a notable deviation from the previous two clean MOT results in 2023 and 2024, suggesting a deterioration in the vehicle’s engine management system or related electrical components. The presence of a recurring advisory about front brake disc wear—though not severe enough to fail the test—indicates ongoing wear that should be monitored closely, as prolonged exposure to such conditions can compromise braking performance and safety. The failure highlights the importance of addressing the engine issue promptly to prevent further degradation, which could escalate into more costly repairs or even render the vehicle unsafe. The recorded mileage of 47,537 miles for a vehicle aged nine years represents a relatively low annual usage rate of approximately 5,282 miles per annum, which is atypical for its age. Such low mileage often suggests periods of prolonged inactivity, potentially leading to issues such as standing corrosion, particularly in the brake systems, suspension components, and undercarriage. The front brake discs showing wear in the MOT history may be exacerbated by infrequent use, as standing brakes can cause corrosion or binding, especially if the vehicle has been left stationary for extended periods. Additionally, the rear tyres displaying minor cracking or perishing in the 2024 MOT could stem from age-related degradation rather than wear from driving, warranting a closer inspection of sidewall conditions for signs of dry rot or internal damage. The absence of higher mileage accumulation over recent years does not necessarily mitigate these risks, as standing vehicles can still suffer from accelerated wear in critical systems. For the prospective buyer, the most urgent concern is the engine malfunction indicated by the MIL, which must be diagnosed and repaired without delay. This failure category is non-negotiable for roadworthiness, and any delay in addressing it could lead to further damage, reduced fuel efficiency, or even a complete loss of power. During a test drive, listen for unusual engine noises such as knocking, ticking, or a loss of power, especially under acceleration or when idling. Check for warning lights that may indicate related issues like low coolant levels, oil pressure, or sensor failures. Beyond the engine, the front brake discs showing wear should be inspected for thickness, surface smoothness, and signs of warping or glazing. Test the braking system for even pedal travel, absence of pulsation or shudder, and proper response to brake application. If the vehicle has been stationary for long periods, inspect the underside for rust, particularly around the brake calipers, wheels, and suspension components, as standing corrosion can compromise structural integrity. In addition to the immediate concerns, given the vehicle’s age and low mileage, the buyer should conduct a thorough physical inspection for age-related issues that may not have been flagged in the MOT. Examine the tyres for sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been stored in poor conditions or exposed to extreme temperatures. Check the 12-volt battery for signs of weakness, such as slow cranking, dimming lights, or corrosion on terminals, as batteries degrade over time regardless of usage. Inspect the fluid levels and condition of the engine oil, coolant, and brake fluid, paying particular attention to their freshness and colour, as fluids degrade over time even with infrequent use. Verify that the service history is up to date, particularly for time-based maintenance such as oil changes, brake fluid flushes, and suspension component inspections, as these are critical for long-term reliability. Finally, consider having a pre-purchase inspection by a qualified mechanic to assess the engine’s condition beyond what the MOT can provide, including testing for leaks, compression, and electrical system integrity.
