2009 Fiat 500 1.4L Petrol · PJ59 JWN

Corrosion on the rear coil springs represents the primary mechanical concern for this vehicle, as evidenced by the most recent MOT test on 06 October 2025. While the vehicle passed its latest inspection, the presence of corrosion on both the nearside and offside rear coil springs was flagged as an advisory following a failure regarding headlamp aim. This indicates a developing issue with the rear suspension components that has emerged after several years of clean MOT results between 2021 and 2024. The vehicle has covered 82,881 miles over its seventeen-year lifespan, which equates to an average annual accumulation of approximately 4,875 miles. This relatively low annual mileage suggests the car has been used for short-distance trips or has spent significant periods stationary. Mechanically, such a pattern can sometimes lead to accelerated corrosion on suspension components and brake assemblies due to limited exposure to road salt cleansing, which aligns with the recent advisories regarding the rear coil springs. Prospective buyers should pay close attention to the rear suspension during a test drive. Given the recorded corrosion on the coil springs, listen for any metallic knocking, clunking, or creaking noises when driving over speed bumps or uneven road surfaces, as this can indicate structural fatigue or failure in the spring or its seating. Additionally, the 2020 advisory regarding light oil misting on the nearside front shock absorber should be monitored; check for any visible dampness on the shock absorber body or any excessive bouncing or oscillation when the vehicle is subjected to vertical movement, which would suggest the damping effect has diminished. The headlamp aim failure noted in the October 2025 test should also be verified to ensure the adjustment mechanism is functional and the beam pattern is correctly aligned for night driving. While the washer jets were previously flagged for misalignment in 2022, ensure the system now provides a consistent and directed spray across the windscreen. Overall, the inspection should focus on the integrity of the suspension components and the presence of any further fluid leaks from the damping units to ensure these recent advisories do not signal more significant mechanical deterioration.
