2014 Mercedes-Benz C 2.0L Diesel · ML64 RZP

The most recent DVSA MOT test on 2025-10-15 returned a clean pass, but this follows a pattern of recurring issues that have occasionally escalated to major failures. While the vehicle has passed most tests without defects since 2024, the presence of persistent advisories—particularly around the near-side front suspension arm wear and offside rear brake binding—suggests underlying wear that may not yet be critical but warrants closer attention. The 2022 and 2023 MOTs also highlighted structural tyre defects, including a dangerous blistered sidewall and soft sidewall wear, which indicate either previous damage or cumulative stress that could compromise tyre integrity over time. These recurring advisories and past failures imply a maintenance trend that has been reactive rather than proactive, with some components approaching or exceeding their functional thresholds. The vehicle’s recorded mileage of 91,501 miles for a 12-year-old Mercedes-Benz C-Class reflects a moderate annual usage rate of approximately 7,625 miles per year, which is typical for its age and likely reflects a mix of daily commuting and occasional longer trips. There is no evidence of rapid mileage accumulation that would suggest aggressive driving or excessive wear on consumables like brakes, suspension, or tyres beyond what would be expected from this usage profile. However, the absence of service records or a service booklet means that fluid degradation—particularly in the brake system, coolant, and differential fluid—could be a concern, especially given the brake-related advisories and past failures. The suspension advisories also suggest that the vehicle may have been subjected to rough road conditions or prolonged periods of standing, which can accelerate wear in suspension components like arms, bushes, and coil springs. Given the recurring advisories and past tyre and brake defects, the prospective buyer should conduct a thorough inspection of the suspension system, focusing on the near-side front suspension arm and its associated bushes. Listen for unusual clunking or rattling noises when the vehicle is driven over bumps or at low speeds, as this could indicate loose or worn suspension components. The offside rear brake binding and fluctuating performance from previous MOTs suggest that the service brake system may be compromised, with potential issues such as binding calipers, warped discs, or worn pads. On a test drive, check for uneven brake pedal travel, pulsations during braking, or a spongy feel, which could indicate hydraulic issues or mechanical binding. Additionally, visually inspect the brake discs for corrosion, scoring, or uneven wear, and ensure the calipers are not binding when the brakes are applied. For the tyres, the buyer should examine the sidewall for signs of cracking, perishing, or dry rot, which can occur even at moderate mileage due to the vehicle’s age. Given the past tyre defects, particularly the blistered sidewall and soft sidewall wear, it is advisable to replace the tyres if they are approaching or have exceeded their legal tread depth, as worn or damaged tyres pose a significant safety risk. Check the tread depth on all tyres, including the offside front inner tyre, which showed soft sidewall wear, and ensure they are within the legal minimum of 1.6mm. Finally, since the vehicle has not undergone a full service in recent years, the buyer should verify the condition of the 12V battery, as prolonged standing or low demand conditions can lead to battery failure. Inspect the battery terminals for corrosion, check the voltage when the engine is off, and ensure the battery is fully charged before use. Time-based fluid servicing, such as the coolant and differential fluid, should also be considered, as these fluids degrade over time regardless of mileage, and their failure can lead to catastrophic engine or drivetrain damage.
