2017 Mitsubishi ASX 3 DI-D 1.6L Heavy oil · ST17 XLP

The Mitsubishi ASX presents a stable and reassuring roadworthiness profile. The most recent test on 14 November 2025 at 44,933 miles resulted in a clean pass with zero defects recorded. This outcome follows a minor anomaly on 13 November 2025, where the vehicle failed at 44,917 miles despite no defects being listed, suggesting a procedural or administrative retest rather than a mechanical failure. The maintenance trend is firmly stable, with no recurring faults, advisories, or serious defects appearing across the entire recorded history. The mileage pattern tells a clear story of exceptionally low use. The vehicle accumulated just 5,870 miles between the November 2022 test at 34,950 miles and the November 2023 test at 39,063 miles, then only 5,870 miles again over the following two years to reach 44,933 miles by late 2025. That equates to roughly 4,993 miles per year across its nine-year life, well below the UK average. The tight clustering of the three November 2025 tests within a single day and a 102-mile window around 44,900 miles indicates the vehicle was likely being prepared for sale or had a minor administrative issue resolved quickly. No gaps or sudden jumps in mileage raise concern. Despite the clean MOT record, a buyer should still inspect the underbody and suspension components in person. Low-mileage vehicles that stand for extended periods can develop seized suspension bushes, corroded brake calipers, and deteriorated rubber components that MOT tests at static inspection may not fully expose. Check the condition of the tyres for sidewall cracking or date codes older than five years, as rubber degrades with time regardless of tread depth. Examine the exhaust system for surface corrosion, particularly around joints and mounting points, and verify that the brake discs and pads show even wear without lipping or scoring. The drivetrain and engine bay deserve equal attention. With only 44,933 miles on the 1.6 DI-D diesel unit, confirm that the diesel particulate filter has not suffered from repeated short journeys, which can cause clogging and costly regeneration failures. Inspect the clutch operation and gearbox for any notchiness, and look for coolant or oil weeping around the engine block and turbocharger connections. A clean MOT history is encouraging, but a hands-on inspection remains essential to confirm that this low-mileage example has been genuinely well cared for rather than simply underused.
