2020 Mercedes-Benz X 2.3L Diesel · EJ20 DYN

The vehicle’s most recent MOT, conducted just over a year ago on 2025-07-10 at 40,585 miles, confirms it passed without defects, indicating a clean roadworthiness status at that point. However, the preceding test cycle reveals a concerning pattern of neglect. The July 2023 failure at 24,678 miles—just 146 miles before the subsequent pass—highlighted multiple critical issues, including worn front brake pads and discs, tyres approaching the legal limit, and a nail embedded in the nearside rear tyre. The fact that these faults were not addressed before the 2023-07-25 retest suggests either rushed repairs or a lack of proper attention to basic maintenance. While the vehicle has since passed two consecutive tests without defects, the 2023 failures underscore a history of deferred upkeep, particularly with consumables and tyre safety. The mileage progression suggests moderate usage, averaging around 6,764 miles annually, which aligns with typical expectations for a vehicle of this age. There are no extreme gaps or sudden spikes in mileage between tests, though the 2023 failure and retest occurred within just 7 days and only 146 miles apart, implying either a rushed correction or a test centre error. The most recent MOT, just over a year old, means the vehicle has not undergone official inspection since, leaving a window where undocumented wear could have developed. The consistent annual mileage also means suspension components, brake calipers, and drivetrain elements—critical for long-term reliability—may now require closer scrutiny, especially if the vehicle has been driven under varied conditions. A buyer should prioritise an independent inspection of the front brake system, given the 2023 failure on worn pads and scored discs. The history of tyre wear, particularly the repeated near-limit tread readings, warrants checking for uneven wear patterns, which could indicate alignment issues or suspension bush deterioration. The nail in the rear tyre in 2023 is a red flag for potential punctures or internal damage; inspecting for silent leaks or uneven tyre pressures is essential. While the windscreen wipers were faulty in 2023, their condition now should be verified, as rubber degradation accelerates with age and exposure. Structural elements like the subframe and rear axle mounts should also be examined for corrosion or loosening, as these are often overlooked but critical for handling and safety. The absence of structural advisories in recent tests does not guarantee their absence entirely, particularly if the vehicle has been exposed to salt or moisture.
