2009 Mercedes-Benz C 2.1L Diesel · M111 AAY

The vehicle shows a worsening maintenance trend characterized by increasing frequency and complexity of mechanical advisories. While the October 2025 test at 90,454 miles resulted in a pass, the record reveals a pattern of neglected consumables and recurring component wear. The vehicle has moved from a period of clean MOT results between 2018 and 2022 to a series of failures and multiple advisories regarding steering, suspension, and braking systems. The mileage profile indicates low annual usage, averaging approximately 5,321 miles per year over its seventeen-year lifespan. This low usage is evident in the steady progression from 51,692 miles in 2020 to 90,454 miles in 2025. However, the low mileage may contribute to the deterioration seen in the records, such as the perished tyres noted in 2015 and the pitting on brake discs, which often occurs when a vehicle spends significant time stationary rather than being driven regularly. A prospective buyer must prioritize a thorough inspection of the braking system and steering components. The tester flagged thinning rear brake pads and pitted rear discs in both the 2024 and 2025 tests, suggesting that brake maintenance is reactive rather than preventative. The steering rack inner joints have shown persistent play since at least 2023, and the 2024 failure for an inoperative engine MIL indicates electrical or sensor issues that require verification. Suspension integrity also warrants close attention. The history shows a progression of faults from deteriorated rubber bushes in 2015 to a failed offside front lower suspension arm ball joint in 2024. Additionally, the 2023 report of corroded rear coil springs where they sit inside the arms suggests potential structural issues with the spring mounts. Given the recurring advisories for worn tyres and edge wear, the alignment and suspension geometry should be checked to ensure the vehicle is not causing premature tyre degradation.
