2008 Mercedes-Benz C 2.1L Diesel · PR04 OOS

This eighteen-year-old Mercedes-Benz C-Class presents an unusual MOT narrative, one characterised not by chronic component failures but by a curious pattern of identical test entries on the same dates. The most recent recorded event on 9 January 2026 shows both a pass and a fail registered, with no defects recorded against either outcome. The same anomaly appears on 13 January 2025, where a pass is followed by a fail entry on 8 January 2025, again with no advisories or failure points listed. A straightforward pass on 4 January 2024 precedes the sequence. The absence of any recorded advisories or mechanical defects across all six entries suggests the vehicle has maintained a clean structural and mechanical record at the point of test, and the dual entries likely reflect administrative retests or data recording irregularities rather than sudden component deterioration. From a roadworthiness standpoint, the lack of flagged corrosion, suspension wear, or brake issues in the official record is a positive baseline indicator. Mileage accumulation on this C-Class sits at 145,420 miles across approximately eighteen years, yielding an annual average of around 8,079 miles. This figure is broadly consistent with typical usage patterns for a vehicle of this age and demographic, suggesting neither prolonged periods of standing nor unusually high wear-inducing mileage. The MOT history does not include recorded odometer readings against each test, which limits the ability to verify whether mileage has been accumulated steadily or in concentrated bursts. For a Mercedes-Benz of this generation and mileage, the engine, automatic transmission, and drivetrain components will have experienced substantial cumulative working cycles, meaning internal wear on items such as the balance shaft, automatic gearbox valve body, and rear diff mount should be considered likely regardless of the clean MOT surface record. Given the complete absence of advisories in the MOT data, there is no specific component history to target during a pre-purchase inspection. However, given the vehicle's age and mileage, particular attention should be directed towards areas commonly affected on the W204 C-Class platform. Suspension linkages and front control arm bushes are known wear items that may not yet have triggered an advisory; on a test drive, listen for clonking or knocking noises over uneven surfaces, particularly from the front end, and feel for vagueness in steering response or uneven tyre wear patterns that might indicate perished bushes or worn drop links. The coil spring perches should be inspected for corrosion, as this was a known weak point on earlier C-Class vehicles, and any visible surface rust around the suspension turrets warrants close examination. The braking system on a high-mileage Mercedes of this era warrants sensory evaluation even though no specific defects are recorded. Test the pedal feel for sponginess, which could indicate perished rear brake flex hoses or corroded brake pipe unions along the underbody and fuel tank area. Listen for any grinding or scraping from the front calipers, which are prone to slider pin seizure on this platform, leading to uneven pad wear and pulling under braking. Under the bonnet, inspect for oil misting or weeping around the cam cover gasket, oil filter housing, and the area around the balance shaft gear, as these are typical leak points. Finally, examine the exhaust system for signs of corrosion at the mounting rubbers and pipe joints, and verify that the central display, air conditioning, and electric seat functions operate correctly, as electronic faults on a vehicle of this age are often the first indicators of broader electrical degradation rather than mechanical concern.
