2009 SEAT Leon 1.6L Petrol · AF59 OAD

A pattern of coil spring failures defines the mechanical profile of this 2009 SEAT Leon. Within the same test on 6 August 2026, the nearside front and nearside rear coil springs were both recorded as fractured, constituting major defects that prevented a pass. A separate pass was issued on the same date only after the defects were presumably addressed, but the test history shows this is not an isolated incident. On 9 August 2022 an offside front coil spring fracture was recorded as a major failure, meaning two separate coil spring breakages have been logged across the recorded history, both occurring on the front axle and one on the rear. Coil spring fractures on a vehicle of this age typically result from corrosion fatigue or extended cyclical loading, and the recurrence strongly suggests that the remaining springs, the related top mounts, and the suspension struts should be regarded as suspect items rather than assumed serviceable. Alongside this, the 2026 test recorded severely deteriorated ball joint dust covers on both front lower suspension arms, a minor defect at the time but a recognised precursor to accelerated joint wear once the internal grease is exposed to road grit and moisture. The mileage profile is unusually low for a seventeen year old vehicle. With 87,951 miles accumulated across approximately seventeen years, the annual rate works out at roughly 5,174 miles, well below the typical figure for a car of this age and class. Testing has been carried out annually without any multi-year gaps, so the vehicle has not been recorded off the road for extended periods, which reduces the likelihood of the brake seizure, fuel system degradation, and brake fluid moisture absorption issues commonly associated with prolonged standing. However, low annual mileage does not insulate the suspension from fatigue; in fact, the recurring coil spring failures across both 2022 and 2026 demonstrate that the springs have reached the end of their functional life regardless of the modest mileage. The brake system has also shown minor concerns, with a 2023 advisory noting rear service brake binding, a condition that tends to worsen on lightly used cars where caliper pistons and slider mechanisms can corrode in situ. Given the established coil spring failures on both front and rear axles, a prospective buyer should treat the entire spring and damper assembly as a priority inspection area. A test drive should be conducted over rough urban surfaces and speed humps, listening specifically for clonking or metallic rattling from the front strut area, which would indicate a further fractured spring or a compromised top mount. The vehicle should also be rocked firmly at each corner with the wheels lifted to check for play in the front lower suspension arms; any looseness, or visible cracking of the rubber bushes, would confirm that the deteriorated dust covers flagged in 2026 have allowed grit ingress into the ball joints. The exhaust system recorded a minor leak at the middle box in 2026 and a tyre cracking advisory in both 2024 and 2025, so the exhaust hangers and joint integrity should be physically inspected for black soot deposits or hissing under cold start, and the tyres should be examined for sidewall cracking as well as tread deterioration. The binding rear brake noted in 2023 warrants particular attention on the test drive. With the engine running and the handbrake released, the vehicle should roll freely on level ground; any tendency for the rear to drag, or a noticeable pulling to one side under light braking, would suggest the rear caliper sliders or pistons have seized since the advisory was issued. The handbrake holding force should also be evaluated on an incline, as low mileage combined with infrequent use can lead to corrosion on the rear drum or caliper handbrake mechanism. Finally, the headlamp lens defect noted as a minor in 2023 should be visually rechecked, as degraded polycarbonate lenses scatter light and reduce night-time illumination, and the small exhaust leak at the middle box should be confirmed as repaired rather than simply masked, since unresolved leaks can lead to catalyst damage and increased cabin noise.
