2012 Citroen DS3 1.6L Diesel · RF61 ABX

The Citroën DS3’s most recent MOT test on 6 March 2026, at 117,449 miles, confirms it remains roadworthy but reveals a pattern of deferred maintenance rather than acute mechanical failure. While the vehicle passed with only a minor nail in the near-side rear tyre, the history shows repeated non-critical failures—particularly around lighting, emissions, and suspension components—suggesting inconsistent upkeep rather than a single catastrophic issue. The most concerning trend is the recurring stop lamp and position lamp faults, which indicate either neglect or a faulty wiring loom, while the anti-roll bar ball joint dust cover deterioration at 110,280 miles hints at suspension wear that may now require closer inspection. Emissions failures in 2024, despite the vehicle being a Euro 5 model, imply either a failing catalytic converter or a misfiring engine, both of which could escalate into more serious problems if ignored. The mileage progression of roughly 8,389 miles per year aligns with typical usage for a vehicle of this age, though the gap between tests—often spanning exactly 12 months—suggests the owner adhered to the MOT cycle rather than proactive servicing. There are no abrupt jumps or prolonged periods of inactivity, but the lack of service intervals between MOTs means critical items like timing belts, spark plugs, or fluid changes may not have been addressed. The consistent presence of a nail in the rear tyre across multiple tests, despite passing, implies either repeated minor punctures or a failure to replace tyres when tread limits were reached. A prospective buyer should prioritise an independent inspection of the suspension, particularly the anti-roll bar linkages and bushings, given the documented deterioration in 2025. The repeated lighting failures warrant a thorough check of the loom and connectors, as well as the rear stop lamps, which failed twice in the past year. Emissions concerns from 2024 should prompt a diagnostic scan for engine misfires or a failing catalytic converter, while the windscreen damage—though not failing—may mask underlying structural cracks or adhesive failure. Corrosion around wheel arches, sills, and suspension mounts should also be scrutinised, as this model is prone to rust in high-mileage examples. Given the vehicle’s age and the pattern of deferred faults, a pre-purchase inspection by a specialist is strongly advised.
