2016 Isuzu D-MAX 2.5L Diesel · HY66 FEP

The most recent DVSA MOT test for this 2016 Isuzu D-Max was conducted on 2 June 2025 and resulted in a pass with no defects or advisories recorded. This outcome, combined with three further consecutive passes in February 2024, February 2023, and January 2022, indicates a notably stable and consistent maintenance trend over the four most recent tests. There is no evidence of recurring advisory items or developing failure patterns in the official record, which is reassuring for a vehicle of this age and working background. However, prospective buyers should bear in mind that a clean MOT history represents only a snapshot of roadworthiness at the time of testing and does not guarantee the absence of wear-related issues that may emerge before the next annual examination, particularly given the high mileage this vehicle has accumulated. The recorded mileage of 178,714 miles over approximately ten years equates to an annual usage of around 17,871 miles, which is considerably above the national average and consistent with a vehicle that has been used commercially or for sustained long-distance work. There are no significant gaps in the recorded test history and no evidence of prolonged standing periods, which is mechanically favourable as it reduces the likelihood of severe corrosion to brake discs, seized calipers, deteriorated fuel systems, or perished rubber components. The high annual mileage does, however, imply greater wear on consumable items such as clutch components, brake pads and discs, suspension bushes, shock absorbers, and drivetrain mounts. The D-Max's leaf-sprung rear suspension and live rear axle are robust, but the constant load and mileage will have accelerated wear on bushes, shackles, and spring eyes, which an MOT inspector may not necessarily flag until play becomes pronounced. For a working vehicle of this age and mileage, several physical checks should be prioritised irrespective of the clean MOT history. Tyre condition warrants close inspection, particularly sidewall cracking or perishing, as the age of the rubber may compromise integrity even if tread depth remains legal; check the date codes on the sidewalls and look for uneven wear patterns that may suggest alignment issues, worn suspension components, or overloaded operation. Brake discs should be examined for lipping and excessive corrosion, particularly around the edges, while the caliper slides and handbrake mechanism should be checked for binding given the high mileage. The 12V battery, cooling system, brake fluid, and gearbox or transfer box oils should all be considered for replacement on a time-based schedule rather than purely mileage intervals, especially as D-Max diesels commonly suffer from cooling system scaling and EGR-related issues that may not be evident on an MOT. A thorough underbody inspection for oil leaks from the engine, gearbox, and front or rear differential seals is strongly advised given the high mileage, along with checks for corrosion to chassis rails and mounting points. On a test drive, listen carefully for suspension clonks or knocking over uneven surfaces, which would suggest worn leaf spring bushes, shackle pins, or anti-roll bar links. Pay attention to any signs of clutch slip under load, grabby or juddering engagement, or difficulty selecting gears, as these indicate wear consistent with high-mileage commercial use. Observe the engine for excessive smoke from cold start or under acceleration, listen for timing chain rattle, and monitor the temperature gauge for any signs of overheating, which is a known concern on older D-Max models. Steering should be checked for play or vagueness, particularly around the straight-ahead position, and the four-wheel-drive system, if fitted, should be engaged to verify smooth operation of the transfer box and front diff. Finally, request evidence of regular servicing, particularly timing belt replacement intervals, as the 2.5-litre diesel engine has a defined belt change schedule, and confirm that the vehicle has been maintained with appropriate quality parts given its evidently demanding service history.
