2018 DS DS7 C-Back Pfrmnc LN Bhdi SS A 2.0L Diesel · KS18 WNU

The vehicle passed its most recent MOT on 20 January 2026 at the recorded mileage, and the immediate prior test on 29 January 2025 also resulted in a clean pass with no advisories logged. Across the five recorded tests since May 2023, only a single failure is noted, dated 30 May 2023, with the vehicle passing on the very next day (31 May 2023) at effectively the same mileage. No advisory text or component notes were captured on either the failure or the subsequent pass, so the precise cause of the original refusal cannot be confirmed from this dataset. The short interval between the failed and passed tests, combined with two further clean outcomes over the following two and a half years, indicates a stable roadworthiness trend with no observable deterioration in the recorded defects. Mileage accumulation sits at approximately 7,100 miles per year over an eight-year lifespan, which is broadly typical for the vehicle's age and not suggestive of either heavy commercial use or extended standing periods. No specific odometer readings are recorded against the individual test entries, so internal consistency of the mileage cannot be independently verified. The absence of MOT entries between December 2023 and January 2025 represents a fourteen-month gap, likely reflecting a postponed test rather than a lapse in compliance, as the January 2026 result confirms ongoing annual testing. Given the relatively modest annual mileage, wear on major mechanical assemblies such as the clutch, turbocharger and diesel particulate filter would normally be expected to progress slowly, though these components do not form part of the standard MOT inspection. From a buyer inspection perspective, the clean advisory history is genuinely positive but offers limited diagnostic insight, as many developing mechanical faults on the BHDi diesel powertrain — including dual-mass flywheel wear, EGR valve carbon build-up and DPF saturation — fall outside MOT scope. A physical inspection should therefore focus on cold-start smoke, dashboard DPF warning indicators and any hesitation under load. The recorded failure of 30 May 2023, although unresolved in detail, occurred at low mileage and was rectified within 24 hours, suggesting a minor component issue rather than a structural concern. Closer examination of the suspension bushes, coil springs and rear brake caliper slides is advisable given the vehicle's age, alongside a thorough check for corrosion on the underbody and around the wheel arches, areas where early corrosion can develop unseen. Finally, a diagnostic code read via the OBD port is essential to confirm the absence of stored emissions or drivetrain faults that the MOT records alone cannot reveal. Buying score: 66. Risk level: Low.
