2012 Mercedes-Benz C250 AMG Sport + CDI Blue-CY A 2.1L Heavy oil · EY12 FSA

The most recent MOT on 2026‑03‑12 failed at 123,888 miles with no defects recorded, indicating a roadworthiness issue not captured in the defect log. The maintenance trend shows a pattern of alternating passes and failures that has intensified over time: a pass in October 2021, a failure in November 2022, a pass the following day, another failure in March 2024, a pass in April 2024, and now a failure in March 2026. This escalating cycle of failures suggests the vehicle’s condition is worsening rather than stabilising. Mileage accumulation has slowed in the last five years, rising from 90,602 miles in October 2021 to 123,888 miles in March 2026 – a gain of 33,286 miles over roughly 4.5 years, or about 7,400 miles per year. Earlier periods, such as the six‑year span from June 2015 to November 2021, saw an average increase of roughly 10,300 miles per year. The testing frequency has also increased, with passes and failures occurring within days of each other in 2022 and 2024, highlighting a reactive rather than preventive maintenance approach. Tyre condition remains the most persistent concern. The June 2018 test flagged near‑side and off‑side front tyres with slight cracking, and both rear tyres worn close to the legal limit. A bulge in the near‑side front tyre was recorded in July 2016, and the windscreen carried an obstruction exceeding the 40 mm allowance. A buyer should inspect all four tyres for bulges, uneven wear, and cracking, verify that rear tyres are not at the wear limit, and check the windscreen for any stickers or obstructions that could affect camera operation. Although no brake or suspension defects appear in the MOT records, the recurring failures suggest underlying mechanical issues. The buyer should test the brake pedal for firmness, check for binding calipers or uneven pad wear, and inspect brake discs for scoring or corrosion. Suspension bushes and shock absorbers should be examined for excessive play or oil leaks, and the chassis should be inspected for rust or corrosion, particularly around wheel arches and underbody panels. A thorough visual check of the exhaust system and under‑body panels is also advisable to confirm the absence of structural deterioration.
