2014 Mercedes-Benz B-Class 1.8L Diesel · Y2 TOO

The most recent MOT, conducted on 23 July 2025 at 64,650 miles, passed with only minor advisories—no critical defects were recorded. However, the trend reveals a pattern of deferred maintenance rather than outright neglect. The July 2024 failure on the nearside rear tyre (a cut exposing ply/cords) suggests basic upkeep was overlooked, yet the subsequent July 2025 test shows no repeat of that issue, implying the tyre was replaced. That said, the severe deterioration of both front anti-roll bar ball joint dust covers—flagged as advisories in 2025—points to prolonged exposure to road grime and moisture, which could accelerate wear on the underlying components if not addressed. The absence of defects in the two preceding passes (2023 and 2022) indicates the vehicle was otherwise roadworthy, but the 2024 tyre failure disrupts an otherwise clean history. The mileage accumulation is unusually low for a 12-year-old vehicle, averaging just 5,388 miles per year. This could reflect infrequent use, extended periods of inactivity, or a combination of both. The gap between the 2022 test (40,486 miles) and the 2023 test (42,347 miles) spans over a year with only 1,861 miles added—a stark contrast to the 10,643 miles covered between 2023 and 2024. Such variability raises questions about whether the vehicle was stored for long periods or driven sparingly. The lack of mileage alone doesn’t guarantee reduced wear, as components like suspension bushes and brake fluid can degrade regardless of distance, particularly if the car was left unused in damp conditions. For a prospective buyer, the front anti-roll bar ball joints demand immediate attention. While the dust covers’ deterioration is an advisory, the underlying joints should be inspected for play or fluid leaks, as prolonged exposure to road debris can compromise their integrity. The 2024 tyre failure—though resolved—warrants checking the remaining tyres for hidden damage, uneven wear, or age-related cracking, especially if they’ve been under-rotated. No brake-related defects appear in the MOT history, but binding calipers or uneven disc wear could still be present. Finally, given the low mileage and potential storage periods, the battery, wheel bearings, and suspension coil springs should be tested for corrosion or stiffness, as these are prone to degradation when a vehicle sits idle.
