2012 Mercedes-Benz C250 Sport CDI Blueeffi-CY A 2.1L Heavy oil · YC12 AEA

The vehicle’s most recent MOT test on June 12, 2025, confirms it passed without defects, though it failed just five weeks prior on May 27, 2025—an unusual pattern given the absence of recorded issues on either test. The preceding clean passes in April 2024 and March 2023 suggest no consistent mechanical failures, but the back-to-back failures in early 2023 and mid-2025 raise questions about either a temporary oversight in pre-test preparation or an intermittent fault that wasn’t fully resolved. The lack of advisories or defects in any test implies no major structural or drivetrain concerns were detected, though the repeated failures without explanation warrant scrutiny of components prone to sudden failure, such as brake systems or suspension linkages. The recorded mileage of 55,149 miles over nearly 14 years equates to an average of just under 4,000 miles annually, which is unusually low for a vehicle of this age. The gaps between tests—particularly the 11-month span between the 2024 and 2025 tests—suggest prolonged periods of inactivity, which could accelerate wear on fluids, seals, and suspension components. The rapid accumulation of 732 miles between the two 2025 failures (May 27 to June 12) is also notable, as it implies either a rushed pre-test repair or a fault that manifested quickly after a period of disuse. Such mileage patterns often correlate with neglect of routine maintenance, such as brake fluid changes or tyre pressure monitoring. Given the absence of specific defect codes in the MOT history, a buyer should prioritise an independent inspection of the brake system, particularly the rear calipers and pads, as binding brakes were a recurring issue in the 2023 failure. The suspension should be checked for worn bushes, coil spring integrity, and corrosion at mounting points, especially if the vehicle has spent extended periods stationary. Tyre condition remains critical—failing twice on tread suggests either repeated delays in replacement or inconsistent maintenance. Finally, the exhaust system and emissions should be examined for leaks or corrosion, as these are common failure points in older Mercedes-Benz models with high mileage but low annual usage. No advisories in the record do not preclude hidden issues, so a thorough mechanical review is essential.
