2015 Smart (mcc) Fortwo 0.9L Petrol · FA15 UPV

A recurring emissions failure dominates the MOT history, with major defects recorded for exhaust carbon‑monoxide levels both at idle and after a fast idle in 2023 and again for a non‑functional engine MIL indicator in 2025. The fact that the vehicle subsequently passed an MOT two days later in August 2025 shows the problem was remedied, but the repeat of the same failure type suggests an underlying issue with the engine management system or catalytic converter that may re‑appear if not fully addressed. The recorded 34,709 mi over eleven years works out to roughly 3,150 mi per annum, well below the typical usage for a car of this age. Such low annual mileage often points to periods of limited use or extended storage, which can accelerate the ageing of rubber components, seals and fuel system elements even as mechanical wear remains modest. The MOT record shows no large gaps between tests, indicating the vehicle has been regularly presented for inspection despite the low mileage. Prospective buyers should focus on the emissions and engine management area. Verify that the check‑engine light remains extinguished and that the engine idles smoothly without hesitation or roughness. A diagnostic scan should be performed to confirm the absence of stored fault codes, particularly those relating to the oxygen sensors, catalytic converter efficiency and fuel trim. During a road test, listen for any irregular exhaust notes and watch for a sudden loss of power under light acceleration, which could signal a lingering catalyst or sensor problem. The brake and tyre advisories from 2020 and 2022 merit close inspection. Although the front brake pads and discs were flagged as thin and pitted in 2020, the MOT passed without defects, implying they may have been replaced; however, a tactile check of pad thickness and disc surface is advisable, and the pedal should feel firm without pulsation. The off‑side front tyre was noted as slightly damaged on the outer edge, so examine the sidewall for cracking, bulges or tread loss, and confirm that the tyre’s age is within acceptable limits. Finally, confirm that the nearside front headlamp is correctly aimed and that the beam does not dazzle oncoming traffic, as mis‑aim was previously recorded. A thorough test drive that includes braking, cornering and steady cruising will reveal any lingering suspension or steering irregularities that the MOT record does not capture.
