2009 Mercedes-Benz C 2.1L Diesel · FG54 FGS

The 2009 Mercedes-Benz C-Class demonstrates a stable maintenance trend, currently holding a strong roadworthiness status. The most recent examination on 27 January 2026 at 164,599 miles passed with zero defects recorded, confirming the vehicle meets all required safety and environmental standards. While a failed test appears in the record on 22 January 2024 at 146,942 miles, the subsequent retest on the same day at 146,948 miles passed cleanly, suggesting any minor issue was promptly rectified. The absence of advisories or recurring mechanical faults across the documented history points to a vehicle that has been kept in sound operating condition. The mileage accumulation aligns perfectly with typical usage for a vehicle of this age, averaging roughly 9,682 miles annually. Between the December 2022 test at 135,242 miles and the January 2024 test at 146,942 miles, the car covered 11,700 miles over thirteen months. The rate then stabilised, with 8,755 miles accrued between January 2024 and February 2025, followed by 8,902 miles over the subsequent twelve months leading to the January 2026 test. This consistent, steady accumulation indicates regular daily use rather than prolonged standing or excessively high-mileage runs, which bodes well for the longevity of the drivetrain and consumables. Despite the clean MOT record, a pre-purchase inspection must focus on the structural and mechanical wear typical of a 17-year-old executive saloon. At 164,599 miles, the front and rear suspension bushes, drop links, and coil springs will likely exhibit fatigue, even if they have not yet triggered a failure. The brake discs and pads should be measured for wear, as high-mileage units often suffer from lipping or reduced friction efficiency. Inspect the subframes and load-bearing areas for corrosion, a common issue for vehicles of this vintage, paying close attention to the condition of the exhaust system and mounting points. The anomaly of the January 2024 failure without recorded defects warrants a specific check of the vehicle's electronic systems and emissions hardware. Request a diagnostic scan to verify the catalytic converter efficiency and ensure no intermittent engine management light faults exist. While the paper trail suggests diligent upkeep, the physical reality of a 164,000-mile Mercedes requires a thorough mechanical audit to confirm the integrity of the chassis and drivetrain before purchase.
