2012 Mercedes-Benz C 2.1L Diesel · FY12 ACO

The 2025‑01‑15 MOT at 246,369 miles resulted in a pass, yet the record reveals a worsening maintenance trend. Earlier tests showed fewer advisories, while the latest inspection flagged front suspension arm ball joint play, oil leakage, a corroded near‑side front coil spring, a cracked exhaust, and near‑side front shock absorbers misted with oil. These recurring defects indicate that previous owners have not consistently addressed mechanical wear, allowing issues to accumulate rather than resolve. The mileage pattern shows high usage for a 14‑year‑old vehicle, averaging about 17,600 miles per year since 2015. Accumulation was relatively steady from 2015 to 2021, with gaps of two years between 2017 and 2019 and again between 2019 and 2021. From 2021 onward the car covered roughly 35,000 miles annually, rising from 158,745 miles in 2021 to 246,369 miles in 2025, suggesting intensified driving or long periods of standing that accelerated component fatigue. A buyer should inspect the front suspension assembly closely, paying particular attention to ball joints, arm pins and bushes, which have repeatedly been recorded as loose or worn. The rear sub‑frame shows persistent corrosion since 2022, and the exhaust exhibits a crack that may worsen. Brake pads and discs have been noted as thin or worn in multiple tests, while the coil spring corrosion and oil leak point to potential hydraulic and structural concerns. Tyre wear patterns and wheel distortion also merit close examination. Overall, the vehicle meets the legal standard in its most recent test, but the concentration of advisories on suspension, braking, chassis corrosion and exhaust integrity suggests that deferred maintenance could lead to costly repairs; a thorough physical inspection of these components is essential before purchase.
