2016 Citroen C4 1.6L Diesel · CA16 GYR

The most recent MOT test on 2025-10-10 confirms this Citroën C4 remains roadworthy, though the preceding cluster of failures in late 2024—two consecutive re-tests within a fortnight—suggests either a temporary oversight in scheduling or a genuine but resolved mechanical issue. The absence of defects in the 2023 and 2025 tests implies the vehicle has not suffered persistent structural or safety-critical failures, but the rapid succession of failures in October 2024 warrants scrutiny. The latest pass, just nine months ago, aligns with the standard MOT cycle, but the earlier re-tests indicate the tester may have identified a non-critical but recurring issue that was rectified before the final pass. The recorded mileage of 135,672 miles over ten years—approximately 13,567 miles annually—exceeds the average for a vehicle of this age, suggesting either consistent use or prolonged periods of higher-than-average mileage. The gap between the 2023 test at 112,839 miles and the first failure in 2024 at 127,951 miles indicates roughly 15,000 miles were accumulated in under a year, a notable acceleration. This pattern could imply the vehicle was actively driven during that period, accelerating wear on components like suspension bushes, brake calipers, and drivetrain fluids. The absence of any advisory notes in the MOT history means no partial failures were recorded, but the high mileage still raises expectations for thorough inspection of high-wear items. Given the 2024 failures, a buyer should prioritise examining the braking system, particularly for binding rear calipers or uneven wear on brake discs, as these are common causes of MOT re-tests. The suspension should be checked for worn or leaking bushes, particularly at the rear, where corrosion or fatigue is more likely to manifest. Given the elevated mileage, the condition of the exhaust system—including catalytic converter integrity and rust penetration—should be inspected, as should the structural underbody for signs of corrosion around wheel arches or sills. The absence of advisories in the MOT history does not preclude these issues, so a visual and functional assessment is essential. Finally, the condition of the tyres, while not directly tied to the failures, should be verified for uneven wear or excessive tread depth, as this could indicate alignment or suspension issues.
