2004 SEAT Leon 1.9L Diesel · FX04 XLK

The vehicle remains roadworthy, but the maintenance trend shows a clear shift towards mechanical wear and structural degradation. While the most recent test in October 2025 resulted in a pass, it introduced multiple minor faults regarding deteriorated drive shaft CV boots. This represents a regression from the 2023 test, which recorded no defects, suggesting that the vehicle's ageing rubber components are now reaching the end of their functional life and require proactive attention to prevent failure. At 148,859 miles, this 22-year-old Leon has averaged approximately 6,766 miles per year. This low annual usage suggests short-distance trips, yet the age of the vehicle is clearly impacting the condition of metalwork. The record shows consistent annual testing between 2022 and 2025, but the presence of recurring steering linkage issues and rust over these four years indicates that the low mileage has not shielded the car from time-related oxidation or typical component de-driven wear. A buyer must prioritise a thorough inspection of the underbody to assess the extent of the corrosion noted in the 2025 advisory. The recurring mention of corroded brake pipes in both 2022 and 2025 suggests a persistent issue with rust lines that could lead to fluid pressure loss if not treated. Furthermore, the steering inner tie rods and rack joints flagged in 2024 should be checked for excessive play, as these components directly affect the steering precision and overall safety of the vehicle. The severely deteriorated CV boots on both front drive shafts identified in 2025 require immediate replacement to avoid grease loss and eventual failure of the drivejoints. While the oil leak noted in the latest test was described as not excessive, the source should be identified to ensure it is not a failing seal that will worsen over time. The vehicle is currently at a stage where rubber components and structural integrity are the primary risks to long-term roadworthiness.
