2016 Citroen C4 1.6L Diesel · BW65 KDV

The vehicle most recently passed its MOT test on 23 March 2026 with no defects or advisories recorded, which is an encouraging immediate indicator of roadworthiness. However, the underlying test history reveals a maintenance pattern that requires careful scrutiny. Across the five-year MOT sequence, there have been two failures, one Dangerous and one categorised alongside dangerous defects, and a recurring advisory regarding rear brake pad wear that appeared in 2021, 2022, and 2023. The 2024 Dangerous failure for rear brake pads less than 1.5 mm thick indicates that the advisory notices were either ignored or that wear accelerated sharply between tests, resulting in a near-complete loss of friction material. Similarly, the 2023 Dangerous failure for a nearside track rod end ball joint worn to the extent of serious detachment risk represents a critical steering component failure that could have resulted in loss of directional control. While the most recent pass is clean, the trend shows that wear items, particularly rear braking components and front suspension geometry, have been progressing more rapidly than routine servicing would typically accommodate. A prospective buyer should treat the clean 2026 result as a baseline rather than a guarantee of underlying condition, and should verify that the rear brake pads, track rods, and any associated components replaced following the Dangerous failures were fitted with quality parts and accompanied by documented service records. With 95,250 miles recorded over approximately ten years, this C4 averages around 9,500 miles annually, which is broadly typical for a vehicle of its age and suggests consistent rather than exceptional use. There are no extended gaps in the MOT record that would indicate prolonged standing, which reduces the likelihood of severe underbody corrosion or seized caliper issues from inactivity. Nevertheless, at this mileage and age, the drivetrain, clutch (if manual), turbocharger (if applicable), and major engine consumables will have undergone significant cumulative wear. The annual mileage being steady rather than excessive is mildly reassuring, but the component failures noted in the MOT history suggest that maintenance quality, rather than simply mileage, has been inconsistent. A ten-year-old diesel or petrol unit at this mileage will benefit from a thorough inspection of timing belt or chain service intervals, coolant and brake fluid renewal, and verification that all manufacturer-recommended servicing has been completed to schedule. The 2025 advisories deserve particular attention as they identify developing wear patterns that may not yet be safety-critical but warrant monitoring. Both nearside and offside front outer constant velocity boots were recorded as severely deteriorated, which is a concerning Minor defect that can lead to rapid grease loss and subsequent joint failure if water or grit ingress occurs. A buyer should inspect the boots for splits, perished rubber, or grease fling around the joint and along the underside of the engine bay, and listen for clicking or knocking noises during sharp low-speed turns on a test drive. The advisories regarding nearside and offside front lower suspension arm rear bushes being worn but not yet resulting in excessive movement indicate the suspension is approaching a service threshold; on test drive, listen for clonking or knocking over speed humps and uneven road surfaces, and check for uneven front tyre wear patterns which would confirm accelerated bush deterioration. Furthermore, the rear child seat advisory across multiple tests restricts proper inspection of rear belt condition, so a buyer should physically verify rear belt operation, retractor function, and buckle integrity before purchase. Beyond the MOT-specific defects, a ten-year-old vehicle with average mileage still requires age-appropriate inspection across several areas. Tyres should be checked for sidewall perishing and cracking from age even if tread depth is adequate, as old rubber hardens and compromises grip regardless of mileage. The 12V battery is highly likely to be approaching or past its service life and should be load-tested, particularly if the vehicle has shown any signs of slow cranking or intermittent starting issues. Brake discs, even those replaced with the pads, may show corrosion or lipping from typical road use, and binding calipers are common on vehicles that see regular short journeys. Fluid degradation should be assumed for brake fluid (which absorbs moisture and should be replaced every two years regardless of mileage), coolant, and transmission oil if the latter has not been serviced within the manufacturer interval. Finally, exhaust system integrity, including mounting rubbers, catalytic converter condition (relevant to emissions compliance), and any evidence of welding repairs, should be examined given the vehicle's age, and a thorough underside inspection on a ramp is strongly recommended to identify any corrosion or fluid leaks not visible from above.
