2012 Smart Fortwo Passion CDI Auto 0.8L Diesel · LR12 WDY

The latest recorded MOT test outcome for this 2012 Smart Fortwo Passion CDI Auto is a pass dated 20 August 2025, though it is worth noting that the same date also carries a fail against an engine MIL indicator issue that was presumably addressed and re-tested to achieve the pass recorded for that day. Looking at the history overall, the vehicle has demonstrated a broadly stable maintenance pattern, passing its annual tests in 2021, 2022, 2023, 2024, and 2025. The defects that have caused failures in 2023, 2024, and 2025 are all isolated, separate issues affecting different systems rather than repeating faults on the same component, which suggests the vehicle has not fallen into a pattern of unresolved mechanical deterioration. Each annual retest has resulted in a pass with no recorded advisories, indicating that wear-related items have either been rectified promptly or have not yet reached advisory thresholds. With a recorded mileage of only 12,843 miles over approximately 14 years, this Fortwo has covered around 917 miles per year on average, which is exceptionally low and indicates significant periods of standing or very light, irregular use. Such low annual mileage is generally favourable for major mechanical components such as the engine, gearbox, and drivetrain, as it limits wear on internal moving parts. However, prolonged standing brings its own concerns, particularly with regard to corrosion seizing on brake calipers and discs, deterioration of rubber components, fluid degradation due to age rather than use, and the natural discharge of the 12V battery. The MOT history shows no dramatic mileage jumps between tests, reinforcing the picture of a vehicle that has likely spent extended periods garaged or otherwise unused, meaning age-related rather than wear-related degradation is the primary concern. Given this usage profile, a prospective buyer should pay particular attention to the condition of the brake discs and calipers. Even though there was an offside rear brake binding failure in 2024, this could suggest early signs of caliper slide pin seizure or a sticking handbrake mechanism common on vehicles that stand for long periods. On a test drive, listen for any grinding or rubbing noises from the wheels when first moving off, as seized calipers can produce audible warning sounds or pull the vehicle to one side under braking. Inspect the brake discs visually for any significant edge corrosion or lipping, which is normal on lightly used cars but should not be so severe as to cause juddering under braking. Confirm the handbrake holds firmly on an incline and releases cleanly, as the cable and ratchet mechanism can corrode internally if rarely used. Given the diesel powertrain, the exhaust system, particulate filter, and turbocharger components warrant inspection for corrosion or seizure from condensation accumulation during cold running cycles typical of short, infrequent journeys. Finally, despite the low mileage, age-related service items remain critical. The diesel engine oil and filter should be changed annually regardless of mileage, and the timing belt, which on this 0.8-litre CDI unit is typically due at five-year or 60,000-mile intervals, should be verified as recently replaced, as rubber deterioration occurs with age alone. Brake fluid and coolant should be renewed based on calendar age, generally every two to three years for brake fluid and four to five years for coolant, irrespective of mileage. The tyres, despite likely having ample tread from low use, should be carefully inspected for sidewall perishing and cracking caused by age and UV exposure, as tyres over six years old can degrade structurally even with plenty of tread remaining. The 12V battery should be load tested, as a battery that has sat partially discharged for long periods will have reduced capacity. Additionally, check for any diesel fuel system leaks around the injectors and fuel lines, ensure the roof hinge mechanism operates smoothly on the cabriolet or targa panels if applicable, and verify that all warning lamps illuminate correctly on ignition, particularly given the recent MIL indicator failure which suggests the diagnostic system should be functioning reliably.
