2015 Fiat Panda 1.2L Petrol · SC15 AYT

A recurring emissions and parking brake concern sits at the centre of this Fiat Panda's MOT history, despite a generally tidy pass record. The car was submitted for test on 26 February 2026 and returned a clean pass with no defects recorded, but on the same date it was also recorded as failing on two Major items: an exhaust carbon monoxide content after the second fast idle exceeding manufacturer specified limits, and parking brake efficiency below requirements. These are functional defects that point to the catalytic converter and lambda sensor on one hand, and to the handbrake mechanism on the other. Given that the three prior tests in 2023, 2024 and 2025 all passed without advisories, the situation suggests two components that may have deteriorated late in the test cycle rather than a chronic history of emissions or brake trouble, although the CO result in particular can be sensitive to a worn catalyst, an ageing lambda sensor, ignition timing irregularities or an air leak in the induction system that may not have been rectified. The recorded mileage of 41,492 miles over an 11-year lifespan equates to approximately 3,770 miles per year, which is low for the vehicle's age. MOT submissions appear at roughly annual intervals from 2023 through 2026, with no extended gaps that would indicate long periods off the road, and the mileage progression between tests is consistent with light, regular use. Mechanically, low annual mileage on a small petrol city car of this type generally means reduced wear on major drivetrain components but can also bring its own risks, including deterioration of rubber seals, brake caliper slide mechanisms and the handbrake cables and shoes due to underuse. The recorded parking brake failure at the most recent test is consistent with a mechanism that has been lightly used and has either seized or rusted at the cable adjusters, the caliper actuators or the rear shoes themselves. For a prospective buyer, the immediate priority is to verify whether the emissions defect and parking brake failure have been professionally repaired with documented evidence, as a Major failure is not a minor advisory and the vehicle should not be considered roadworthy without the work being completed to a satisfactory standard. On a road test, listen for any irregular idle from the exhaust note, hesitation or a slightly rough idle that could indicate the catalyst or lambda sensor is still degraded, and watch the CO reading on a retest if one is obtained. For the handbrake, apply it firmly on a slope and confirm it holds without creeping, and listen for any ratcheting or grinding from the rear hubs that could point to a seized cable, corroded caliper actuator or self-adjusting mechanism that has stuck. Inspect the rear brake shoes and drums for wear ridge and corrosion, and check that the cable operates smoothly through its outer sheath. Beyond the two flagged items, the absence of any suspension, steering, corrosion or tyre advisories across four recorded examinations suggests the underbody, coil springs, shock absorbers and bushings are not showing visible deterioration at test level, although these items should still be physically inspected on a ramp or over a wheel-free lift given the Panda's known susceptibility to rear axle corrosion and front suspension arm wear. Carry out a thorough test drive over uneven road surfaces, paying close attention to any clonking or knocking from the front suspension, any pulling under braking which could indicate binding calipers, and any play or vagueness in the steering that might suggest worn track rod ends or drop links. Confirm the handbrake holds on an incline, allow the engine to idle from cold and watch for excessive smoke or an unstable tick-over, and ensure the clutch action is smooth without slipping under load, as low-mileage clutches can develop hydraulic issues from standing unused.
