2009 Mercedes-Benz C 2.1L Diesel · OV59 NVM

The most recent MOT test on 11 December 2025 resulted in a pass, though this follows a failure on the immediately preceding date of 10 December 2025, indicating that remedial action was undertaken specifically to clear the test. The fail items included a fractured nearside front coil spring and a nearside rear tyre with a cut exposing ply or cords, both classed as major defects, alongside advisories and minor items relating to anti-roll bar linkage dust covers and a damaged inner sidewall on the offside rear tyre. The current pass carries an advisory for an offside brake pipe corroded but covered in grease or other material front to rear, an issue that has recurred in multiple previous tests. Overall, the trend suggests the vehicle is being maintained to a passable standard but with persistent advisories around brake pipe corrosion and accumulating suspension component wear, which warrants close scrutiny rather than assumption of sound mechanical health. At 157,364 miles over approximately seventeen years, this C-Class has accumulated roughly 9,257 miles per year, which is broadly typical for a car of this age and consistent with regular everyday use rather than long periods of standing or excessive high-mileage driving. There are no significant gaps in the MOT testing record, suggesting continuous use and annual exposure to the test cycle, and the relatively even progression of mileage points to a car that has been driven consistently rather than left idle or subjected to severe duty cycles. The mechanical implications of this mileage bracket on a seventeen-year-old Mercedes include well-worn suspension and bush components, tired braking hardware, and accumulated corrosion on underbody and pipework, all of which align with the advisories recorded. The recurring advisories on the brake pipework, noted in 2022, again in 2022, in 2021, and now in 2025, should be treated seriously even though they have consistently been recorded as corrosion covered in grease rather than structural failure. On a test drive, listen for any soft or spongy brake pedal feel, uneven braking response, or any pulling to one side under braking, and inspect visually beneath the vehicle for signs of fresh seepage, flaking, or sections of pipe that look paper-thin or pitted. The anti-roll bar linkage dust cover deterioration noted as a minor in 2023 and again in 2025 points to ageing rubber bushes that will likely require replacement in the near future and may manifest as knocking or clunking over uneven road surfaces or during direction changes. The fractured nearside front coil spring recorded on the recent failure is a known wear item at this mileage and age, and replacement in pairs is advisable to maintain balanced handling; any sagging at the front corners or audible clonking over bumps should be investigated. Beyond the recorded defects, a prospective buyer should carry out age- and mileage-appropriate checks given the vehicle is seventeen years old. Inspect all four tyres for sidewall cracking and perishing even if tread depth is adequate, as rubber degrades with age regardless of mileage, and check the spare or emergency repair kit if fitted. Examine brake discs for lipping, corrosion, or binding calipers which are common on vehicles used for shorter journeys or those standing for periods. Verify the 12V battery condition, as units of this age frequently hold reduced charge, particularly if the vehicle has been stood between MOT tests. Confirm the timing belt or chain service interval has been observed according to Mercedes-Benz schedule, check that the service book contains stamps or digital records at appropriate intervals, and inspect coolant, brake fluid, and automatic transmission fluid for time-based degradation. Finally, examine the exhaust system, given the recorded flexi pipe failure in 2021, and confirm any replacement work was carried out to a satisfactory standard, while also checking for oil leaks from the engine and automatic gearbox seals which become more prevalent at this mileage.
