2015 Citroen C4 1.6L Diesel · FP15 LSC

The most recent DVSA examination on 19 January 2026 resulted in a clean pass with no advisories or defects recorded, which is a positive immediate indicator. However, evaluating the trajectory across the available history reveals a pattern that warrants careful attention. The 2024 test produced a fail related to lighting defects which were rectified, while the 2022 test included a major exhaust insecurity issue. Across multiple years there has been a steady accumulation of advisories relating to suspension arm pins and bushes at the front, brake disc wear across both axles, and repeated reports of binding rear brake mechanisms. While each individual advisory was not deemed serious enough to cause failure at the time, the recurrence of similar components year on year suggests progressive wear in the braking and suspension systems which a prospective buyer should investigate thoroughly before purchase. With 91,432 miles accumulated over approximately eleven years, this C4 has covered an annual average of around 8,312 miles, which sits comfortably within the typical usage bracket for a vehicle of this age. There are no extreme gaps in the recorded mileage between consecutive tests, indicating the car has been in regular rather than occasional use, which generally limits the risk of calendar-based deterioration such as seized calipers from prolonged standing or severe underbody corrosion from inactivity. The consistent annual accumulation also means consumables such as brakes, tyres, and suspension components have been worked, but there is no evidence of motorway-heavy high-mileage abuse that would disproportionately stress the drivetrain or clutch. Given the recurring advisories on front suspension arm pins and bushes, a test drive should include driving over uneven surfaces and speed bumps to listen for clonking or knocking noises from the front end, as well as checking for vague steering response or uneven front tyre wear which would indicate the bushes have progressed past the advisory threshold. The brake disc wear advisories across both front and rear axles, alongside the persistent binding issues on the rear calipers, warrant a thorough inspection of the braking system. On the test drive, listen for any scraping, grinding, or squealing under light braking, feel for any vibration or shudder through the pedal, and verify the car does not pull to one side under firm application. The rear caliper binding history specifically suggests the offside rear mechanism should be examined for sticky pistons, and the handbrake operation should be checked for full release, as seized calipers lead to uneven pad wear, overheating, and reduced fuel efficiency. Beyond the recorded defects, the age of this vehicle dictates several age-related inspections that may not be fully captured by the MOT data. The tyres should be closely inspected for sidewall perishing and cracking, as rubber degrades over time regardless of tread depth. The 12-volt battery should be tested for cranking strength, particularly if the car has been used for short journeys given the moderate annual mileage. Brake fluid, coolant, and automatic transmission fluid if applicable will all be due for replacement on calendar intervals rather than mileage, so verify the service book for evidence of recent fluid changes. The rear beam axle corrosion advisory from 2023 should be visually inspected on a ramp to ensure it has not progressed to a serious structural concern, and given the history of exhaust insecurity, the mounting rubbers and system integrity should be checked for any rattles on start-up or under load.
