2012 Mercedes-Benz C 2.1L Diesel · KP61 WDK

Repeated initial test failures followed by immediate successful re-tests define the recent MOT history of this Mercedes-Benz, suggesting that the vehicle frequently requires minor rectifications to meet roadworthiness standards. Although the most recent inspection on 26 June 2025 resulted in a clean pass, the preceding two failures in the spring of 2025 indicate a pattern where the car does not consistently maintain compliance on its first presentation. This cycle of failing and passing within short timeframes has persisted since 2021, reflecting a recurring need for adjustments or repairs to ensure the vehicle remains legally compliant for road use. Accumulating 174,824 miles over fourteen years results in an average annual usage of approximately 12,500 miles, placing this vehicle well above the typical mileage profile for its age. This consistent, high-intensity usage suggests that the drivetrain, suspension, and chassis components have been subjected to significant operational stress throughout the vehicle's life. While the MOT records do not explicitly detail specific component failures, the high mileage necessitates a rigorous inspection of all high-wear items, as the mechanical fatigue on major assemblies is substantial compared to lower-mileage examples of this model. Prospective buyers should conduct a thorough test drive to identify potential issues with the suspension and steering geometry, which often suffer from accelerated wear at this mileage. Listen carefully for metallic knocking or clunking sounds when navigating uneven road surfaces, as these symptoms often indicate worn control arm bushes, ball joints, or anti-roll bar links. Given the vehicle's history of intermittent test failures, ensure that the steering feels precise with no excessive play or pulling to one side, and verify that the vehicle tracks straight under both acceleration and braking to rule out underlying structural or alignment concerns. The braking system and exhaust integrity warrant close scrutiny during a physical inspection, as these components are frequently subject to wear that may not be captured in a simple pass-or-fail record. Check for any grinding or juddering sensations through the brake pedal, which could point to warped discs or seized calipers, and inspect the underside for any signs of corrosion on the subframe or brake lines. A cold-start assessment is also advised to listen for any abnormal rattling from the exhaust system or timing chain, as high-mileage Mercedes-Benz engines of this era require confirmation that these critical components remain within their operational tolerances.
