2009 Citroen C4 1.6L Diesel · AJ59 YCD

The Citroen C4 currently holds a failed MOT status from the 29 October 2025 test at 123,277 miles, with the DVLA record showing no defects listed against that failure. Prior to this, the vehicle passed every annual test from 21 October 2021 through 15 October 2024 with no advisories or defects recorded at each interval. The maintenance trend appears stable across four consecutive clean passes, then breaks abruptly with the most recent failure, though the absence of recorded defects leaves the exact cause unresolved from the data alone. Annual mileage averaged 7,252 across the car's 17-year life, a typical figure for the age. The records show steady accumulation: 87,182 miles in October 2021, rising to 94,720 by October 2022, 107,608 by October 2023, and 115,717 by October 2024. That is roughly 7,000 to 8,000 miles added each year. The jump to 123,277 miles by October 2025 adds only 7,560 miles, so no rapid accumulation or standing gap is evident. The clean pass history with zero advisories suggests previous owners kept basic statutory testing compliance, though a total absence of advisories across four years on a car of this age is unusual and may reflect lenient testing rather than flawless condition. A buyer must establish why the October 2025 test failed before any purchase. The DVSA entry records no defects, which can mean a documentation error, a late cancellation, or a failure logged without fault detail. Inspect the vehicle in person for structural corrosion on subframes and sills, worn suspension bushes, and brake disc condition, as these commonly escape advisory notation yet fail later tests. Verify the actual test certificate and VOSA failure sheet. Given the clean 2021 to 2024 record, no recurring mechanical fault pattern emerges from the data. The single unexplained failure at 123,277 miles is the only warning sign. Treat the car as mechanically unknown until the October 2025 failure reason is confirmed and a fresh test is passed.
