2014 Mercedes-Benz C 2.1L Diesel · ML64 RYF

The most recent MOT test on 2026-08-20 resulted in a pass, though it included several persistent advisories that suggest ongoing but manageable wear and minor mechanical issues. When reviewing the full history, the trend over the past two years is neither significantly improving nor worsening—rather, it reflects a pattern of recurring advisories related to suspension components, brake systems, and fluid leaks, with no major failures in the last two tests. The 2024 failure, which included a dangerous near-side rear hydraulic brake calliper leak, stands out as an outlier, indicating a critical failure that required immediate attention, though the vehicle has since passed subsequent tests with only minor advisories. This suggests that while the vehicle has been maintained to meet roadworthiness standards, underlying wear in critical areas like suspension bushings and brake components demands proactive monitoring. The vehicle’s recorded mileage of 162,877 miles at 12 years old is exceptionally high for its age, averaging approximately 13,573 miles annually—a rate that far exceeds typical usage patterns for a similarly aged Mercedes-Benz C-class. Such high mileage accelerates wear on consumables such as brake pads, suspension components, and lubricants, particularly in areas prone to heat and mechanical stress. The absence of significant mileage gaps implies consistent, heavy use, which can exacerbate issues like brake pad thinning, suspension bush degradation, and fluid degradation over time. While lower mileage vehicles may benefit from less wear, this car’s usage profile demands heightened scrutiny of wear progression and potential long-term consequences, especially in the drivetrain and braking systems. Given the recurring advisories and high mileage, the prospective buyer should prioritise a thorough inspection of the suspension system, focusing on the rear and front suspension arms, ball joints, and shock absorbers. Listen for clunks or rattles during cornering or over bumps, as these may indicate worn suspension bushings or loose components. Inspect the brake system for uneven wear patterns, which could signal binding calipers or hydraulic issues, and check for any vibration or shuddering when braking, which may point to warped discs or contaminated brake fluid. The central oil leak and rear park brake inefficiency from previous MOTs warrant attention; ensure all seals are intact and the parking brake mechanism is functioning smoothly to prevent further wear or safety risks. Additionally, verify that the brake fluid is fresh, as standing fluid can corrode brake components over time. For fluid and component checks, the buyer should also inspect the engine oil, brake fluid, and coolant for signs of degradation or contamination, as these are critical in a high-mileage vehicle. Given the underbody corrosion advisories, particularly in the 2025 MOT, examine the vehicle’s undercarriage for rust progression, especially around wheel arches and beneath the rear axle, as this can compromise structural integrity. Check the 12V battery for signs of weakness, such as slow cranking or electrical gremlins, as older vehicles are more susceptible to battery failure. Lastly, since the vehicle has not been serviced for several years, consider a comprehensive mechanical service that includes a full fluid top-up, filter replacement, and inspection of the exhaust system for leaks or emissions-related issues. If the tyres were severely worn in 2022, replace them with new or reconditioned ones to avoid further safety risks, as exposed cords or uneven wear can lead to sudden failure.
