2007 Citroen C4 1.6L Diesel · NH07 JHA

The Citroën C4’s MOT history presents a stark contrast between its mechanical record and its recent testing outcome. Despite passing three consecutive annual tests without defects—most recently in October 2023 at 93,464 miles—the vehicle failed its October 2024 retest at 100,458 miles, yet with no recorded faults. This abrupt failure, occurring just months before the current date in July 2026, suggests either a deliberate MOT manipulation (such as test evasion or a "clean sweep" prior to sale) or an oversight in the DVSA system. The absence of advisories or defects across four tests spanning 2021–2023 implies either meticulous maintenance or a vehicle that has been driven minimally, masking underlying wear. The lack of any documented issues in the official record raises immediate red flags for a buyer, as even minor advisories would typically appear on a vehicle of this age and mileage. The mileage pattern reinforces suspicions of irregular use or selective reporting. Over the past five years, the C4 has accumulated just 19,494 miles—an average of roughly 3,900 miles per year—despite being 19 years old. This is exceptionally low, even for a lightly used vehicle, and the consistent annual mileage increments (around 6,500 miles between tests) suggest the odometer may not reflect true usage. The absence of mileage spikes or drops between tests further implies the vehicle may have been parked for extended periods or, more critically, that the odometer has been tampered with. Without service records or independent verification, a buyer cannot reliably assess whether the engine, transmission, or suspension have been subjected to normal wear patterns. Given the clean MOT history but the recent failure, a prospective purchaser should prioritise a thorough pre-purchase inspection focusing on structural integrity and hidden wear. Key areas demand scrutiny: the suspension components—particularly the coil springs, anti-roll bars, and bushings—should be checked for fatigue or corrosion, as these are prone to failure in vehicles with low recorded mileage but potential age-related degradation. The braking system, including calipers, pads, and discs, must be inspected for uneven wear or binding, as the 2024 failure without defects may indicate evasion of a critical advisory. Exhaust emissions and the catalytic converter should also be verified, as these often trigger failures when neglected. Finally, the underbody and wheel arches must be examined for signs of rust or repair, as corrosion is a common issue in older Citroën models and could compromise safety or longevity. The lack of documented faults in the MOT history does not equate to a well-maintained vehicle. The abrupt failure in 2024, combined with the unusually low mileage accumulation, warrants extreme caution. Without transparent service records or evidence of regular maintenance, the true condition of this C4 remains unverifiable, and the risk of concealed defects—particularly in structural and safety-critical components—is significant. A buyer should treat this as a high-risk purchase unless accompanied by comprehensive, third-party inspection and service documentation.
