2015 DS DS4 1.6L Diesel · PL15 AAO

The most recent MOT test dated 6 July 2026 recorded a pass with no defects, which is positive, but this must be considered alongside the failed test submitted on the same date immediately prior, where both front tyres were deemed dangerous due to exposed plies or cords. The fact that the vehicle passed after the tyres were replaced indicates the underlying issue was rectified at the point of test, yet the broader MOT history reveals a slightly worsening pattern. In 2024 the vehicle passed with no advisories, while in 2025 it suffered a failure for a fractured offside front coil spring alongside advisories for front tyres worn to the legal edge and pitted front brake discs. The recurrence of front-end advisories across consecutive tests, culminating in a dangerous defect for the tyres in 2026, suggests that the front suspension, steering, and braking components have been under elevated stress or have not been inspected and serviced with sufficient regularity between tests. The recorded mileage of 61,410 miles on an eleven-year-old vehicle equates to an annual average of approximately 5,583 miles, which is well below the typical UK usage of 7,500 to 10,000 miles per year. This low usage rate carries its own mechanical implications, particularly with respect to components that degrade through standing rather than wear. Brake discs and calipers can corrode or seize from prolonged inactivity, leading to uneven braking or pulling under pedal pressure, while the 12V battery is highly susceptible to sulphation and reduced capacity if the vehicle has stood for extended periods between short journeys. Coolant, brake fluid, and even engine oil can also deteriorate through age rather than mileage, reducing their protective qualities and increasing the risk of internal corrosion or moisture ingress within braking and cooling systems. Given the recurring advisories relating to front tyre wear, brake disc pitting, and the coil spring failure, a prospective buyer should carry out a focused physical and dynamic inspection of the front suspension and braking system. On a test drive, listen for clonks or knocks over uneven surfaces which could indicate worn suspension bushes, drop links, or strut top mounts, and pay close attention to brake pedal feel, watching for any shudder, vibration through the steering wheel, or pulling to one side which could suggest warped or excessively corroded discs or a binding caliper. Inspect the inner and outer sidewalls of all four tyres carefully for perishing or cracking, as the low annual mileage and age of the vehicle make age-related rubber degradation a real possibility even where tread depth appears acceptable. Where the vehicle has stood for long intervals, verify the battery date stamp and consider a load test, check that all brake calipers release cleanly without dragging, and confirm the condition and age of the brake fluid, coolant, and any timing or cambelt service evidence. Finally, although the MOT record is broadly limited in scope, the existing data points should not be taken as a complete reflection of the vehicle's mechanical condition. The absence of recorded advisories on items such as the clutch, gearbox, turbo, or electrical systems does not imply they are free from wear, particularly given the low annual mileage and age profile. Confirm the authenticity of the recorded mileage through service book stamps, previous invoices, or independent verification, as gaps or inconsistencies could indicate clocking. Inspect the underside and inner arches for corrosion, which is particularly relevant given the DS4's known susceptibility to surface rust in damp conditions, and check for oil or coolant leaks from the engine, power steering, and suspension dampers. A pre-purchase inspection by a qualified independent garage, including a diagnostic read of any fault codes and a borescope examination of the brake discs, would be highly advisable given the combination of age, low recorded mileage, and the recurring front-end defects observed during MOT testing.
