2009 Mercedes-Benz C 2.1L Diesel · RE09 FEM

The Mercedes-Benz C-Class in question presents a stable roadworthiness record over the past three years, with the most recent MOT test in October 2024 at 160,335 miles passing without any defects. This consistency suggests the vehicle has been maintained to meet minimum legal standards, though the absence of advisories or minor defects in the latest tests leaves little insight into proactive servicing beyond compliance. The single failed test in September 2022—also at 150,751 miles—is anomalous, as no defects were recorded, which may indicate a clerical error or a test centre oversight rather than a mechanical issue. Given the clean slate in subsequent tests, there is no evidence of recurring problems or deteriorating components, but the lack of advisories also implies that routine wear items, such as suspension bushes or brake fluid condition, were not flagged for attention. The mileage accumulation of approximately 9,431 miles per year aligns with typical usage for a vehicle of this age, though the data reveals a notable gap between the 2021 and 2022 tests, where mileage increased by just 11,132 miles over 12 months—a slower pace than the preceding years. This could reflect reduced usage, storage, or an error in mileage recording. The most recent 4,186 miles covered between September 2023 and October 2024 suggest either light recent use or a delay in testing. Without advisories or defects, it’s impossible to determine whether this slower mileage accumulation correlates with deferred maintenance, but the absence of major issues in the MOT history does not rule out the need for a thorough pre-purchase inspection, particularly given the vehicle’s age and the typical wear patterns of its generation. For a prospective buyer, the primary focus should be on components not routinely checked during MOTs, such as the condition of the suspension coil springs, rear shock absorbers, and steering rack seals, which can degrade without triggering a fail. The braking system—particularly the rear calipers—should be inspected for binding or uneven wear, as older Mercedes models of this era are prone to caliper sticking or seized slides. Structural corrosion, especially around the sills, wheel arches, and exhaust mounts, is another critical area, given the vehicle’s age and the potential for moisture ingress in poorly maintained examples. While the MOT history shows no defects, the lack of advisories may mask deferred servicing, so a pre-purchase inspection by a Mercedes specialist is strongly advised to verify the condition of the engine bay components, such as the timing belt and auxiliary belts, which are high-wear items on this model.
