2016 Hyundai I40 Premium Crdi Blue Drive 1.7L Heavy oil · R777 FSW

The Hyundai i40 Premium CRDI in question presents a clean MOT history over its recent testing cycle, with the most recent examination on 26 March 2025 at 121,431 miles showing no defects—an outcome mirrored in the three preceding passes from February 2024 (114,414 miles) and October 2022 (99,246 miles) . This consistency suggests the vehicle has maintained stable roadworthiness under its current ownership, with no recurring advisories or failures to indicate deteriorating mechanical integrity. The sole anomaly is the October 2021 fail at 85,925 miles , which lacks recorded defects, implying either a clerical oversight or a minor, unlogged issue resolved before retesting. Given the absence of repeated advisories on critical components—such as suspension bushes, brake binding, or structural corrosion—the vehicle appears to have been well-maintained in terms of compliance with MOT standards. The mileage accumulation, however, raises a notable concern: 121,431 miles over roughly 10 years averages 12,143 miles per annum , which is high for a vehicle of this age and model. The gaps between tests are irregular, with 15 months between the 2021 fail and the 2022 pass , suggesting either infrequent use or delayed retesting. More critically, the 6,983-mile jump between February 2024 (114,414 miles) and March 2025 (121,431 miles) —a span of just 13 months —indicates recent heavy usage, which may accelerate wear on consumables like tyres, brake pads, and clutch components. The lack of advisories in recent tests does not preclude hidden wear, particularly in high-stress areas such as the exhaust emissions system (DPF/EGR) , coil springs , or wheel bearings , all of which can degrade without immediate MOT repercussions. For a prospective buyer, the absence of defects in the MOT record is encouraging, but the high mileage and irregular testing intervals warrant a thorough pre-purchase inspection. Priority should be given to brake system components , including caliper condition, disc thickness, and pad wear , given the vehicle’s age and mileage. The suspension should be checked for worn bushes, leaking dampers, or uneven tyre wear , as these often precede MOT advisories. Underbody corrosion —particularly around wheel arches, sills, and exhaust mounts—should be scrutinised, especially if the vehicle has been driven in harsh conditions. Finally, given the CRDI diesel engine’s reliance on fuel system integrity , a compression test and inspection of injection pump health would be prudent, as diesel engines at this mileage can develop internal wear without obvious external symptoms. The clean MOT history is a positive sign, but the mileage and testing gaps demand vigilance.
