2015 Hyundai I800 2.5L Diesel · NU15 WFR

The 2015 Hyundai i800 presents a stable and recently improving maintenance trend. The most recent test on 12 June 2026 at 156,468 miles passed with zero defects recorded, which is a significant turnaround from the recurring brake pipe corrosion advisories seen in previous years. The tester also noted an internal headlight adjuster alteration in both 2025 and 2023, suggesting a persistent beam alignment issue that has since been rectified. The 2023 failure for an offside front headlamp aim and a non-functioning nearside front position lamp was passed on the same day, indicating the previous owner addressed electrical faults promptly rather than ignoring them. This vehicle has covered approximately 14,224 miles per year, which is high for an eleven-year-old commercial vehicle. The mileage accumulation is consistent, jumping from 129,767 miles in August 2023 to 140,223 miles by September 2024, then to 147,848 miles by August 2025, and finally reaching 156,468 miles by June 2026. This steady climb points to sustained heavy use rather than long periods of inactivity, meaning drivetrain, suspension, and braking components have endured continuous loading. The MOT record itself is clean and well-documented with no gaps, giving a reliable picture of the vehicle's recent history. Despite the clean 2026 result, the recurring corrosion on brake pipes demands attention. The offside front brake pipe was flagged as corroded and contaminated with grease or other material in August 2025, and the offside rear brake pipe received the same advisory in September 2024. Both advisories reference condition 1.1.11 (c), which relates to brake pipe corrosion or damage. A buyer should physically inspect all brake lines, particularly along the offside, for pitting, surface rust, or any signs of fluid seepage. The presence of grease or contamination on the 2025 advisory is unusual and could indicate a previous repair attempt or contamination from a leaking joint rather than simple surface corrosion. Beyond the braking system, a thorough underbody inspection is advisable given the high mileage and commercial nature of this vehicle. Check the rear propshaft joint area, which was specifically referenced in the 2025 advisory, for play or corrosion. Examine suspension bushes, coil springs, and shock absorbers for wear consistent with 156,000 miles of load carrying. The repeated headlight adjuster alterations suggest the aim mechanism may be worn or the mounting points could have been disturbed, so verify that both headlamp units sit securely and that beam pattern remains stable over bumps. Tyre condition and tread depth should also be checked, as high annual mileage on a heavy van accelerates consumable wear considerably.
