2016 Citroen C3 1.6L Diesel · AF16 KCE

The most recent MOT test on 2026-01-28 returned a pass, with the vehicle retaining roadworthiness despite persistent advisories on brake disc wear across all four positions. Over the past six years, the MOT history demonstrates a pattern of recurring but non-failing advisories—particularly concerning the front and rear brake discs, which have been noted for pitting, scoring, and edge wear without compromising structural integrity. While earlier tests in 2020 and 2021 showed no defects, the advisories from 2022 onward indicate a gradual but consistent deterioration in brake system components, suggesting either prolonged low-speed operation or suboptimal braking habits that accelerate disc wear. The absence of critical failures or structural issues in the intervening years suggests that the vehicle remains mechanically sound, though proactive maintenance is warranted to mitigate further disc degradation. The recorded mileage of 57,815 miles for a ten-year-old C3 is notably low, averaging just 5,782 miles per year—a rate that could imply limited operational use or extended periods of inactivity. Such low mileage often correlates with increased risks of standing corrosion, particularly on brake components, exhaust systems, and underbody parts exposed to moisture. The vehicle’s wear profile suggests that consumables like brake pads may have been replaced infrequently, allowing discs to wear unevenly and develop the pitting and scoring observed in the MOT records. Additionally, prolonged standing can lead to fluid degradation—such as brake fluid absorption of moisture or coolant freezing in the radiator—requiring calendar-based servicing to prevent long-term damage. As a prospective buyer, the most critical areas to inspect are the brake system and associated components. Begin by visually examining the brake discs for signs of excessive warping, cracking, or uneven wear beyond the advisories noted in the MOT history. During a test drive, listen for uneven braking performance, such as a shudder or pulsation that could indicate warped discs or binding calipers. Check for fluid leaks around the brake master cylinder, caliper seals, and wheel cylinders, as well as the condition of brake fluid—if it appears dark or has absorbed moisture, it should be replaced. The low mileage suggests potential issues with standing corrosion; inspect the exhaust system for rust or cracks, particularly around the catalytic converter and tailpipes, and check the undercarriage for signs of rust progression on suspension components, struts, or the vehicle’s frame. For broader mechanical checks, verify the tyre tread depth and sidewall condition, as the 2025 MOT advisories on front tyres being worn close to the legal limit warrant attention. Look for signs of sidewall cracking or perishing, which can compromise tyre integrity over time, especially with low mileage. Test the 12V battery’s health by attempting to start the engine and checking for any electrical gremlins, as prolonged inactivity can lead to battery failure. Finally, ensure that all fluids—oil, coolant, and transmission fluid—are topped up to manufacturer specifications, as low-mileage vehicles can suffer from fluid degradation due to stagnation. If possible, review the service history for any recorded brake pad replacements or disc resurfacing, as these records will confirm whether the recurring advisories have been addressed.
