2010 SEAT Leon 2.0L Diesel · ST10 HDN

The roadworthiness of this vehicle is currently poor, showing a significant worsening trend in mechanical condition. The most recent test in October 2024 at 190,035 miles resulted in a comprehensive failure with a high volume of critical structural and mechanical defects. While the vehicle passed in 2023 at 171,703 miles, the subsequent failure revealed a major exhaust leak, serious structural corrosion on the rear suspension arms, and multiple issues that indicate a decline in preventative maintenance. At 190,035 miles, the 16-year-old vehicle has averaged approximately 11,877 miles per year, which is consistent with typical UK road usage. However, there is a notable gap in records between June 2022 and October 2023, during which time the car covered over 18,000 miles. The rapid accumulation of nearly 20,000 miles between the 2023 and 2024 tests likely accelerated the wear on the components flagged in the final high-mileage inspection. A buyer must exercise extreme caution regarding the structural integrity of the car. The history shows a persistent progression of rust, moving from minor subframe corrosion in 2020 and 2023 to seriously weakened rear lower suspension arms in late 2024. Any physical inspection should focus on the depth of this corrosion on the subframe and all trailing arms, as these are high-cost repairs. Additionally, the steering rack inner joints and multiple ball joint failures suggest the front suspension geometry is nearing the end of its functional life. The braking system also requires close scrutiny due to recurring issues with binding, corroded brake hoses, and pitted discs. The 2024 failure highlighted a front oil leak and an insecure exhaust system, suggesting that under-carriage maintenance may have been neglected. Given the high mileage and the nature of the recent failures, the buyer should verify that all flagged repairs from the October 2024 test have been completed with quality parts rather than temporary fixes.
