2015 Citroen C4 1.6L Diesel · LS15 AOP

The Citroën C4’s most recent MOT test on 2025-07-31 confirms it passed without defects at 105,715 miles, though the preceding failure on 2025-07-22—just nine days earlier—indicates a rushed or overlooked pre-test service. This pattern of back-to-back tests in July 2025 suggests the vehicle was pushed through MOTs without addressing underlying issues, as no defects were logged in any of the five tests spanning 2024–2025. The absence of advisories or recurring faults in the record implies no major mechanical trends, but the repeated failures at similar mileages (84,719 to 85,883 miles) raise suspicion of deferred maintenance, particularly in areas like suspension alignment or brake wear that aren’t always captured in MOT failures. The mileage progression reveals a steady but unremarkable accumulation of 9,610 miles annually, consistent with typical usage for a vehicle of this age. There are no prolonged gaps or abrupt spikes in mileage, which would otherwise signal neglect or excessive wear. However, the clustering of three MOT tests within a single month in 2024 and 2025—each failing at nearly identical mileages—suggests the owner may have prioritised passing the test over addressing potential wear patterns. This behaviour could mask underlying issues such as worn suspension bushes, binding calipers, or minor corrosion that might not trigger a fail but could compromise long-term reliability. Given the lack of recorded defects, an in-person inspection should focus on components frequently overlooked in MOT testing: the rear suspension bushes and coil springs for uneven wear or perishing, binding rear brake calipers (a common silent failure), and the subframe or wheel arches for corrosion that could weaken structural integrity. The absence of advisories also warrants scrutiny of the exhaust system for leaks or catalytic converter efficiency, as these are often flagged only during emissions testing. Tyre tread depth and uniformity should be verified, as the repeated failures in 2024 (though no defects were noted) might imply past neglect in this area. Finally, check for oil leaks around the engine bay or transmission mounts, as these are not routinely inspected during MOTs but can indicate serious wear.
