2009 Mercedes-Benz C 2.1L Diesel · KW09 CLZ

The vehicle remains roadworthy but the maintenance history indicates a worsening trend in suspension and chassis-related wear. While the most recent test in June 2024 at 106,144 miles passed, the record reveals multiple mechanical defects that suggest deferred maintenance on aging components. Specifically, the offside front anti-roll bar linkage and lower suspension arm ball joints appeared across both the 2023 and 2024 tests, showing that the front-end suspension geometry is reaching the end of its functional life. The mileage pattern is consistent with a 17-year-old vehicle, averaging approximately 6,200 miles per year. There is a steady accumulation of roughly 4,000 to 5,000 miles between annual tests from 2021 to 2024. This relatively low annual usage has not prevented the natural degradation of rubber components and metalwork. The presence of a persistent but non-excessive oil leak recorded from 2021 through to 2024 indicates a long-term engine seal issue that has not been rectified despite the low distance driven. A buyer must conduct a thorough physical inspection of the rear sub-frame, as the tester noted corrosion in 2023 that persisted into the 2024 report. While not yet deemed seriously weakened, structural rust on a Mercedes of this era progresses rapidly if left unchecked. The corroded front brake pipe covered in grease in 2024 is a specific concern, as the grease masks the true extent of the metal thinning. Furthermore, the recurring inner-edge tyre wear noted in both 2022 and 2024 suggests a persistent alignment issue or worn suspension bushes that require immediate attention to prevent premature tyre failure.
