2011 Mercedes-Benz C 2.1L Diesel · AS07 ANJ

The most recent MOT test on 2026-05-18 resulted in a passing outcome, though it highlighted a persistent minor defect in the near-side front anti-roll bar ball joint dust cover, which has been noted in two previous tests (2024-05-02 and 2025-04-28). While the vehicle has otherwise maintained a clean MOT history since 2023, the recurring advisory on the near-side rear suspension ball joint with slight play (2024-05-02) suggests a developing mechanical issue that may require closer attention. The 2020-09-17 failure—marked by ABS and electronic stability control (ESC) faults—indicates a pattern of electronic system failures, though the vehicle has since passed subsequent tests, implying either corrective action or a transient issue. Overall, the maintenance trend appears stable but warrants vigilance, particularly regarding suspension integrity and brake system corrosion. The vehicle’s recorded mileage of 113,530 miles for a 2011 model year represents a reasonable annual usage rate of approximately 7,569 miles per year, which is typical for its age and likely reflects a mix of general road travel and occasional longer trips. The absence of significant mileage gaps suggests consistent ownership, but the wear progression observed in the MOT history—particularly on tyres, brakes, and suspension components—reflects the cumulative effects of this usage. Tyre wear advisories, including edge wear and cuts, point to either aggressive driving habits or underinflation, which can accelerate tread degradation and compromise handling. The brake system advisories, such as corroded brake pipes and worn but not excessively thin brake discs, indicate potential standing corrosion from moisture exposure, which could lead to leaks or reduced braking performance if left unaddressed. For a prospective buyer, the most critical areas to inspect during a test drive and physical examination include the suspension components, as the near-side front anti-roll bar ball joint and rear suspension ball joint show signs of wear or deterioration. Listen for unusual clunking or rattling noises from the suspension during cornering or over bumps, which may indicate loose or failing bushings or ball joints. The near-side rear tyre cut could suggest recent impact damage or improper repair, so verify the tyre’s structural integrity and check for any irregular wear patterns that might indicate misalignment or alignment issues. Inspect the brake system thoroughly, including the brake pipes for corrosion and leaks, and listen for any grinding or squeaking noises that could signal worn brake pads or binding calipers. Additionally, check for uneven tyre wear, which may indicate alignment or steering component issues that require immediate attention. Beyond the test drive, a thorough inspection should include a visual and tactile assessment of the vehicle’s structural integrity, particularly around the wheel arches and suspension mounts, for signs of rust or damage. Given the vehicle’s age and mileage, the brake fluid should be replaced every two years, as standing fluid can degrade over time, compromising braking efficiency. The battery should be tested for strength, especially if the vehicle has been stationary for extended periods, as corrosion or weak terminals can lead to starting issues. Finally, verify that all service records are up to date, particularly for fluid changes, as the 2020 failure highlighted potential electronic system issues that may have been resolved but require ongoing monitoring. The tyre sidewall should be checked for signs of cracking or perishing, which can indicate long-term exposure to UV radiation and reduce tyre lifespan.
