2015 Mercedes-Benz A-Class 1.5L Diesel · SM65 AFX

The Mercedes-Benz A-Class in question demonstrates a stable roadworthiness trend over the past five MOT cycles, with no defects recorded in any of the tests conducted between March 2023 and March 2026. The most recent test on 2026-03-24—just four months ago—confirms the vehicle passed without fail, despite an unusual duplicate entry for the same date and mileage. This suggests the tester may have inadvertently duplicated the record, but the absence of any advisories or defects across all tests indicates the vehicle has consistently met minimum legal standards. However, the duplicate entry warrants verification that no undocumented issues were overlooked during that inspection. The recorded mileage of 52,165 miles over 11 years—approximately 4,742 miles annually—is unusually low for a vehicle of this age, particularly given the A-Class’s typical usage patterns. Between March 2023 and March 2026, the vehicle accumulated just 11,844 miles, averaging around 3,948 miles per year, which implies prolonged periods of inactivity. The largest gap between tests occurred between March 2025 and March 2026, where the vehicle sat idle for a full year without movement, raising questions about potential fluid degradation or component wear from prolonged storage. While low mileage generally correlates with reduced mechanical stress, the extended periods without use could have allowed for minor issues—such as brake fluid absorption, battery sulphation, or suspension lubricant breakdown—to develop undetected. Given the clean MOT history, a buyer should prioritise an in-person inspection focused on components that degrade passively over time rather than mileage. The suspension system—particularly the rear coil springs and bushes—should be examined for signs of dry rot or excessive play, as these can deteriorate even with minimal movement. Brake calipers and discs should be checked for corrosion or uneven wear, as prolonged inactivity can accelerate rust formation. The exhaust system must be inspected for leaks or structural corrosion, especially around flanges and joints, which are common failure points in older Mercedes models. Additionally, the battery and fluid levels (brake, coolant, power steering) should be verified, as stagnation can compromise their condition. The absence of advisories in past tests does not preclude these areas from requiring attention, particularly given the vehicle’s irregular usage pattern.
