2011 Mercedes-Benz C 2.1L Diesel · BV61 AFJ

The vehicle’s most recent MOT history reveals a concerning instability in its roadworthiness, particularly in the final three months of 2026. Despite passing the February 2025 and February 2024 tests without defects, the car failed twice in quick succession at the end of 2026, both at the same mileage of 126,660—an anomaly that suggests either a critical component failure or a test centre error. The lack of recorded defects in either failure is unusual, as even minor issues are typically logged, which raises suspicion that the vehicle may have been driven unsafely between tests or that the testers overlooked serious faults. The March 2026 pass, just six days after the second failure, further complicates the pattern, as it implies either a rapid resolution of an undocumented issue or a deliberate bypass of necessary checks. This erratic trend warrants immediate scrutiny of high-wear components and structural integrity. The mileage progression of 126,660 miles over five years—approximately 8,444 miles annually—falls within the expected range for a vehicle of this age, though it suggests consistent use rather than neglect. The gap between the February 2025 (120,779 miles) and February 2024 (110,393 miles) tests shows a steady accumulation of roughly 10,386 miles per year, which aligns with typical driving patterns. However, the identical mileage at both the February 2024 failure and pass (110,348 and 110,393 miles) indicates the test may have been retaken immediately after failure, a practice that could mask underlying issues. There are no prolonged periods of inactivity or unusually high mileage spikes, but the lack of pre-failure advisories in the 2024 or 2026 cycles suggests either deferred maintenance or a history of ignoring early warning signs. Given the failed tests without recorded defects, a buyer should prioritise an independent inspection of the braking system, suspension, and exhaust emissions. The repeated failures at the same mileage hint at potential issues with binding rear calipers, worn suspension bushes, or failing coil springs—components that often degrade around this mileage without visible external signs. Corrosion in wheel arches, subframe, or sills should also be checked, as structural integrity deteriorates over 15 years even with moderate mileage. The absence of advisories in recent tests may indicate the vehicle has been driven with compromised safety features, so thorough brake pad and disc condition, tyre tread uniformity, and steering alignment checks are essential. The most recent pass does not negate the need for a detailed mechanical assessment.
