2016 Fiat 500 1.2L Petrol · PE16 DFJ

A persistent exhaust‑leak issue, reinforced by repeated advisories and a recent failure on the lambda‑sensor reading, together with chronic tyre‑wear warnings, dominate this 2016 Fiat 500’s MOT history. The vehicle failed its February 2026 test for an out‑of‑spec lambda signal, a minor exhaust leak and tyre wear on both axles, yet it passed a subsequent test only four days later, indicating that the immediate faults were remedied but the underlying tendency to develop exhaust and tyre‑related defects remains evident. Earlier records show a major rear coil‑spring fracture in 2024 and ongoing shock‑absorber bush wear in 2022, suggesting that suspension components have required attention over the past few years. At 55,207 mi the car averages roughly 5,500 mi per annum, a mileage level that is low for a ten‑year‑old vehicle. Such limited use can reduce cumulative wear on drivetrain and brake parts, but age‑related degradation of rubber, bushings and tyre compounds still progresses, as reflected by the tyre‑wear advisories despite the modest mileage. The MOT chronology shows no prolonged gaps, implying the car has been regularly tested each year, which helps to surface age‑related defects early. Prospective buyers should focus on the exhaust system: listen for hissing or ticking sounds at idle and under load, inspect for black soot around the manifold and check that the lambda sensor operates within the normal voltage range during a short road‑run. Verify that any previous exhaust‑leak repair was comprehensive, as a lingering leak can affect emissions and fuel efficiency. Tyre condition warrants immediate attention; both front and rear tyres were flagged as close to the legal limit and worn on the edges, so a full tyre replacement is advisable and the wheel alignment should be checked to prevent uneven wear. The rear coil spring that fractured in 2024 should have been replaced—confirm the part number and mounting integrity, then test for any clunking or a change in ride height when driving over bumps. Finally, the shock‑absorber upper‑mount bushes noted as slightly worn in 2022 may now be approaching the end of their service life; during a test drive, feel for excessive bounce, a loose feeling in the rear, or any knocking noises when traversing uneven surfaces. Ensure all external lamps, particularly the off‑side registration plate lamp that was previously inoperative, function correctly. A thorough visual inspection of the suspension mounting points and a professional check of the rear spring and shock assemblies will provide confidence that the vehicle’s structural and ride‑quality issues have been fully resolved before purchase.
