2012 Mercedes-Benz C 2.1L Diesel · YC12 ABV

The vehicle currently presents a questionable roadworthiness status following a failed test on February 19 2026 at 133,465 miles. While the car maintained a clean record for several years, the most recent failure without recorded defects suggests a significant mechanical failure or emissions-related issue that prevented a pass upon presentation. The maintenance trend appears unstable, as the transition from a clean pass in April 2025 to a failure in early 2026 indicates a developing fault that now requires immediate attention. The mileage pattern remains consistent with a fourteen-year-old vehicle, averaging approximately 9,500 miles per annum. Between March 2023 at 107,569 miles and March 2024 at 118,281 miles, the car covered 10,712 miles, showing a standard usage profile. However, the narrow gap between the March 24, 2025 failure at 126,972 miles and the April 2, 2025 pass at 126,982 miles shows only 10 miles driven between those tests. This suggests a minor repair, such as a bulb replacement or a sensor adjustment, was sufficient to rectify the initial failure during that period. A buyer must investigate the specific cause of the February 2026 failure, as the lack of recorded defects in the history is unusual for a failed test. Given the age and mileage, a physical inspection should focus on structural integrity and corrosion on the subframe and mounting points. You should also check the suspension bushes and control arms for perished rubber components, as these are common wear points on this model at this mileage. The braking system requires checking for binding calipers and disc thickness to ensure that the recent failure did not stem from a broader degradation of the braking hardware.
