2009 SEAT Leon 2.0L Diesel · OM51 BYE

The vehicle is currently roadworthy, but the maintenance trend shows a shift toward increasing mechanical wear and structural degradation. While the car maintained clean records between 2021 and 2023, the most recent test in September 2025 at 144,209 miles identified multiple advisories. This indicates that the vehicle is entering a phase where age-related component fatigue and corrosion require proactive attention to prevent future test failures. The recorded mileage of 144,209 miles reflects an average of approximately 8,500 miles per year, which is consistent with typical usage for a 17-year-old vehicle. The progression is steady, with a jump of roughly 7,000 miles between the 2022 and 2023 tests and another 7,000 miles between 2023 and 2025. This consistent usage suggests the car has been driven regularly rather than left to sit, which generally helps prevent internal engine issues or seizing. A buyer must prioritize a thorough inspection of the suspension and underbody corrosion. The September 2025 test flagged a worn offside front coil spring, a nearside front Macpherson strut pin or bush, and corroded rear suspension arms. These issues suggest that the structural integrity of the running gear is beginning to decline. Furthermore, the corroded nearside front bumper mountings should be monitored for further metal rot that could ensure the bodywork does not become loose. Braking and tyre condition also require scrutiny. The 2020 record noted pitted rear brake discs, and the 2025 advisory highlighted a nearside rear tyre worn to the legal limit with uneven edge wear. The buyer should check the remaining depth on all tyres and inspect for alignment issues that might be causing the uneven wear. Given the insecure battery noted in the latest test, ensuring the mounting tray is firmly fastened is essential to prevent damage during vibration or operation.
