2009 Mercedes-Benz C 2.1L Diesel · HN09 OGW

The vehicle is currently roadworthy following its most recent pass on 28 February 2026 at 143,520 miles, but the maintenance trend is worsening. The most recent test was preceded by two failures in quick succession, including a failure on 10 January 2026. The current certificate carries a heavy list of advisories, including a corroded rear sub-frame, an oil leak, and corroded brake pipes. These issues indicate a vehicle that is being patched to pass the minimum legal standard rather than being proactively maintained. The mileage is typical for a 17 year old car, averaging roughly 8,442 miles per year. There is a notable increase in usage between January 2024 and January 2025, where the odometer rose from 126,453 to 135,918 miles. The record shows a clean history from 2018 to 2020, but a sharp decline in mechanical condition began appearing in the records from December 2021 onwards. A buyer must prioritize a thorough inspection of the chassis and braking system. The rear sub-frame was flagged as seriously weakened in December 2022 and remains a point of concern as of February 2026. Recurring corrosion on both front and rear brake pipes since 2021 suggests a systemic failure to address rust. The January 2026 failure for a fractured offside front coil spring and exposed tyre cords indicates a dangerous neglect of basic safety consumables. Further attention is required for the drivetrain and steering. The February 2026 test flagged play in the steering rack inner joints and an oil leak that has persisted since January 2025. Excessive exhaust smoke noted in the most recent test suggests potential engine wear or emissions system failure. Combined with worn inner suspension arm bushes on both sides, the vehicle likely requires significant investment in suspension and steering components to restore its original handling and safety.
