2014 Mercedes-Benz B-Class 1.5L Diesel · VU14 AEY

The most recent MOT test on 2026-03-05 confirms the vehicle remains roadworthy, with no defects recorded at 82,228 miles. The absence of advisories or repeated failures across the last four tests suggests a stable maintenance history, though the single failure in May 2025—despite identical mileage—indicates a potential administrative oversight rather than a mechanical trend. No structural or safety-critical components were flagged in the latest test, but the brief retest window (three days between failure and retest) warrants scrutiny of whether the issue was genuine or procedural. The recorded mileage of 82,228 miles over 12 years equates to approximately 6,852 miles annually, a rate consistent with typical usage for this vehicle’s age. There are no concerning gaps in testing, though the near-identical mileage at the 2025 failure and retest (75,625 miles) suggests either a short-term layoff or a minor oversight in scheduling. The steady progression of mileage—rising by around 3,000 miles between each test—implies regular use without aggressive driving, which could mitigate excessive wear on suspension bushes, coil springs, or drivetrain components. A buyer should prioritise a thorough inspection of the suspension system, particularly the rear bushes and coil springs, given the vehicle’s age and mileage. The lack of recorded defects does not preclude gradual degradation in these areas, which often manifest as uneven tyre wear or a stiff ride. Brake discs and calipers should also be checked for uneven wear or binding, especially if the vehicle has been driven hard in recent years. Structural corrosion, particularly around the wheel arches and sills, is another critical area to assess, as it can compromise the vehicle’s integrity over time. Finally, the exhaust system should be examined for leaks or excessive rust, as emissions-related failures are not uncommon in this model at this mileage.
