2009 Citroen C4 1.6L Diesel · NV58 KBZ

The most recent MOT history for this 2009 Citroën C4, tested just eight months ago on 2025-09-30, reveals a concerning inconsistency rather than a clear trend. Despite passing the test at 79,525 miles, the record shows a duplicate entry—one marked as failed—without any defects logged. This anomaly alone raises questions about either an administrative error or, more critically, whether the vehicle was driven to the test without addressing underlying issues. The previous clean passes in 2024 and 2023 suggest no recurring mechanical failures were formally documented, but the lack of defects in any test does not guarantee absence of wear. The absence of advisories or minor faults in the last two cycles implies the vehicle has not been subjected to the typical wear-and-tear checks that might reveal suspension bushes, coil springs, or brake caliper binding—components that often fail silently before MOT thresholds are breached. The mileage progression over the past three years—accumulating roughly 2,430 miles annually—is unusually low for a vehicle of this age, averaging just over 600 miles per month. This suggests either minimal use or prolonged periods of inactivity, which could accelerate certain forms of degradation, such as corrosion in underbody components or suspension seals drying out. The gap between the 2023 and 2024 tests, where mileage increased by only 2,700 miles in a year, further implies the vehicle was not driven consistently. Such low mileage can mask deeper issues; for instance, fluid levels in the power steering, transmission, or cooling systems may have been overlooked, leading to premature failure of non-consumable parts. The identical test dates in 2023 (22nd and 27th September) for the failed and passed entries at nearly identical mileages (74,357 and 74,396) is particularly odd and warrants scrutiny—it may indicate the vehicle was retested without intervening repairs. Given the lack of documented defects, a buyer should prioritise an independent inspection of high-wear areas that often fail without MOT-level symptoms. Focus on the suspension—check for cracked or perished bushes at the control arms, sway bar links, and subframe mounts, as these rarely trigger MOT failures until they are severely degraded. The brake system demands attention: while no binding calipers were recorded, rear brake wear can go undetected until discs or drums are dangerously thin, particularly if the vehicle has been stood for extended periods. Examine the underbody for corrosion at wheel arches, sills, and the rear subframe, as low mileage does not preclude rust from developing in areas exposed to road salt or moisture. Finally, verify the condition of the exhaust system for leaks or broken hangers, as these can lead to catalytic converter damage over time without immediate MOT consequences. The absence of advisories in recent tests does not preclude these issues, so a thorough mechanical assessment is essential.
