2016 Citroen C4 1.6L Diesel · SF66 VMO

The most recent MOT history for this 2016 Citroën C4 reveals a concerning instability in roadworthiness just prior to the current test date. The vehicle failed its inspection on 2025-07-16 at 103,034 miles with no recorded defects, only to pass the subsequent retest on 2025-07-21 at 103,035 miles. This pattern of a single retest without explanation suggests either a minor oversight in the initial test or a last-minute correction by the previous owner. The preceding MOTs, from 2024-05-02 and 2023-12-01, show no defects, indicating a stable period of compliance before the recent volatility. The absence of advisories or recurring issues in the earlier tests implies that, historically, the vehicle had not exhibited systemic failures in brakes, suspension, or emissions—though the retest anomaly warrants scrutiny. The mileage progression for this vehicle aligns with typical usage for its age, averaging around 10,300 miles annually. However, the gap between the 2022-12-05 test at 71,433 miles and the 2023-12-01 test at 87,954 miles represents an unusually high accumulation of 16,521 miles in just under a year. While this could reflect consistent driving habits, it also suggests accelerated wear on high-mileage components such as suspension bushes, coil springs, and brake calipers. The subsequent intervals, from 2023 to 2024 and 2024 to 2025, show more moderate mileage increases—around 5,500 miles each—indicating a possible reduction in usage or a period of lower mileage accumulation. This inconsistency alone does not signal immediate failure, but it does imply that certain parts may have endured more stress than average. Given the lack of defects in earlier MOTs, a buyer should prioritise a thorough inspection of the suspension system, particularly the rear suspension components, as binding or worn bushes or springs are often the cause of retest failures without explicit fault codes. The brakes, though not explicitly flagged, should be checked for uneven wear or binding calipers, especially if the vehicle was driven heavily in the 2023-2024 period. Corrosion at wheel arches, subframes, and sills—common in Citroën models of this age—should be assessed for structural integrity, as unseen rust can compromise safety-critical elements. The emissions system, while passing all tests, may benefit from a diagnostic scan to rule out intermittent faults that could explain the retest anomaly. Finally, the tyres, though not recorded in the MOT history, should be inspected for tread depth and uneven wear, as the high mileage in 2023 suggests they may have been pushed beyond their optimal lifespan.
