2014 Mercedes-Benz B-Class 1.5L Diesel · DX14 VGD

This Mercedes-Benz B-Class has demonstrated a stable roadworthiness trend over the past four years, with no recurring defects or advisories recorded in any of its MOT tests. The most recent inspection on 12 December 2025 at 86,476 miles confirmed no issues, though the vehicle narrowly avoided failure just ten days earlier at 86,328 miles—suggesting either a last-minute correction or a minor oversight in pre-test checks. The absence of any advisory notes across all tests implies that major components like suspension bushes, coil springs, or binding calipers have not been flagged as failing or requiring attention. However, the failure on 2 December 2025—despite no recorded defects—raises a question about whether the test focused solely on overt failures or if subtle issues (such as emissions or minor corrosion) were overlooked. The mileage progression of approximately 7,200 miles per year aligns with typical usage for a vehicle of this age, though the gap between the 2024 and 2023 tests (5,561 miles in a year) suggests a period of reduced activity. The final 6,168 miles between December 2024 and December 2025 indicate consistent driving, but the abrupt failure just before the latest pass—with no defects noted—may hint at a rushed or incomplete pre-test service. There is no evidence of aggressive mileage accumulation or prolonged neglect, but the lack of service records means critical intervals for suspension, brakes, or drivetrain components cannot be confirmed. Given the clean MOT history, a buyer should prioritise an independent inspection of the suspension system, particularly the rear calipers and bushes, as binding brakes were not explicitly ruled out in the failure. The absence of advisories does not guarantee these components are sound, and wear on coil springs or subframe mounts could have gone unnoticed. Brake discs and pads should be measured for uneven wear, as repeated failures on emissions or brakes (even if not recorded) might indicate a history of deferred maintenance. Finally, check for corrosion at wheel arches, sills, and the underbody, as rust can compromise structural integrity without immediate MOT consequences. The vehicle’s age and mileage suggest consumables like wiper blades, brake fluid, and cabin filters may also require replacement.
