2014 Citroen DS4 2.0L Diesel · AF64 ESG

The most recent DVSA examination on 8 October 2025 returned a PASS, though two advisories were issued against the vehicle. One relates to light oil misting on the offside front shock absorber, and the second notes corrosion affecting the rear coil springs. While the test outcome is technically satisfactory, the presence of these advisories signals the early stages of component degradation that warrants attention before purchase. Looking back through the recorded history, the DS4 has passed every annual examination since 2019, with only one failure recorded in September 2020 concerning an inoperative registration plate lamp. However, the advisory count has been gradually increasing in recent years, moving from no defects recorded in 2019 and 2020, through minor advisories in 2021 and 2022, to the more mechanically significant coil spring corrosion and shock absorber oil misting noted in 2025. This trend indicates a vehicle that is progressively accruing wear-related issues consistent with advancing age and mileage, rather than a sudden deterioration. With 152,230 miles accumulated over approximately 12 years, this DS4 is averaging around 12,686 miles per year, which is notably high for a vehicle of its age. There are no extended gaps in the recorded mileage to suggest prolonged periods of standing, indicating that the car has been in regular and sustained use throughout its life. This level of utilisation places considerable wear on the entire drivetrain, suspension, braking system, and engine components, meaning that consumable parts such as clutches, dual-mass flywheels (if fitted), turbochargers, and timing chains will have been subjected to substantial working cycles. Buyers should anticipate that major mechanical servicing may be due or overdue, particularly given that high-mileage diesel and petrol powertrains of this era frequently require significant attention beyond 150,000 miles. Regarding the specific advisory items, the light oil misting on the offside front shock absorber suggests that the unit's internal seals are beginning to fail. While this is not yet at a failure threshold, it is a progressive condition that will worsen over time. On a test drive, the buyer should listen for clonking or knocking noises from the front suspension over uneven surfaces, excessive body roll through corners, and any nose-diving behaviour under braking, all of which would suggest the unit has deteriorated further. The corroded rear coil springs are a more concerning advisory, as corrosion weakens the spring steel and can ultimately lead to fracture, particularly under load or over speed humps. A thorough physical inspection underneath the vehicle is essential, ideally with the car raised on a ramp, to assess the extent of corrosion on all suspension components, including the front springs, which were not specifically mentioned but are subject to the same environmental exposure. Should the springs appear heavily pitted or flaking, replacement should be budgeted for. Beyond the documented advisories, the high annual mileage and 12-year age of this DS4 necessitate a comprehensive inspection of several age-related items. Brake discs and pads should be examined for wear, with particular attention to disc lipping and pad material thickness, given the 2022 advisory noted front brake disc corrosion. All tyres should be inspected not only for tread depth but also for sidewall cracking or perishing, as older tyres degrade regardless of mileage. The 12-volt battery is likely due for replacement given its age, and starting behaviour should be observed for any hesitation or slow cranking. Engine oil, coolant, brake fluid, and power steering fluid should all be assessed for condition and service history, as these degrade over time irrespective of mileage. Finally, the timing belt or chain replacement interval should be verified against the manufacturer's schedule, as neglecting this on a high-mileage PSA-sourced engine can result in catastrophic failure. A pre-purchase inspection by a competent independent garage, ideally including a diagnostic scan for stored fault codes and an underbody examination, would be strongly advisable given the vehicle's age and accumulated wear.
