2012 MERCEDES-BENZ CLS250 CDI BLUEEFFICIENCY AUTO2.1L Diesel

The vehicle's recent MOT history shows an inconsistent trend, culminating in a failure during the most recent test on 9 March 2026 at 127,496 miles. While the car passed without defects in March 2025 at 112,950 miles, the subsequent failure in November 2024 at 111,268 miles and the most recent failure in March 2026 suggest an intermittent issue that has not been resolved. The lack of specific defect descriptions in the digital record makes it difficult to pinpoint the exact mechanical failure, but the pattern indicates the vehicle is not currently meeting minimum roadworthiness standards. The mileage accumulation appears consistent with a typical usage pattern for a 14-year-old vehicle, averaging approximately 9,100 miles per year. The data shows a steady progression from 60,230 miles in November 2022 to 127,496 miles in 2026. This gradual increase suggests regular road use rather than long periods of stationary storage. The jump from 60,230 miles in late 2022 to 105,278 miles in late 2023 represents a significant period of higher usage, which often correlates with increased wear on suspension bushings, dampers, and braking components. A prospective buyer must investigate the specific cause of the failure recorded in March 2026. Given the age and mileage, a thorough inspection of the underbody for structural corrosion is essential, particularly around the subframes and suspension mounting points. The recurring failures without recorded advisories suggest that issues may be appearing suddenly rather than developing gradually through minor wear. Physical inspection should focus on the integrity of the suspension system and the condition of the brake discs and calipers to check for binding or excessive thinning. The buyer should also verify that the recent failure has been rectified with documented evidence of repairs. Without knowing the specific reason for the 2026 failure, the vehicle should be considered a high-risk purchase until the exact mechanical or structural fault is identified and addressed.
