2019 Mercedes-Benz X 3.0L Diesel · NG19 EFR

The most recent MOT test on 2025-05-22—just over a year ago—confirmed the vehicle’s roadworthiness at 104,977 miles, with no defects recorded. This suggests the car passed all mandatory checks for brakes, suspension, emissions, and structural integrity at that point. However, the history reveals a pattern of repeated failures at the same mileage intervals: both the 2023 and 2024 tests were conducted twice on the same date, with the second attempt passing. While this does not indicate active mechanical failure, it implies administrative delays rather than recurring technical issues. The absence of advisories or recurring faults in the most recent tests suggests the vehicle was brought up to standard before each MOT, though the lack of defects does not preclude hidden wear. The mileage progression indicates unusually high annual mileage, averaging nearly 15,000 miles per year over seven years—a rate significantly above the UK average for this vehicle class. Between the 2023 and 2024 tests, the odometer jumped by 21,403 miles in just under a year, suggesting either intensive use or a period of active driving. The gap between the 2025 test and today (over a year) is standard for MOT intervals, but the lack of intermediate maintenance records raises questions about whether routine servicing was consistently performed. Such mileage demands greater scrutiny of high-wear components like suspension bushes, coil springs, and brake calipers, which may not have been replaced proactively. Given the clean MOT history without advisories, the primary focus for an in-person inspection should be the suspension system, particularly the rear bushes and coil springs, which are prone to fatigue at this mileage. The repeated MOT attempts at the same intervals in 2023 and 2024 could hint at minor oversights in pre-test preparations, but the absence of defects suggests these were not structural issues. Brake discs and pads, given the mileage, should be checked for uneven wear or binding calipers, while the exhaust system warrants inspection for corrosion or leaks, especially if the vehicle has been driven in wet conditions. The lack of advisories in recent tests does not guarantee all components are in perfect condition, so attention to fluid levels (brakes, power steering, coolant) and tyre tread depth—despite passing MOTs—is essential.
