2009 SEAT Leon 2.0L Diesel · KP09 TFN

Recurring suspension and exhaust component issues define the mechanical profile of this SEAT Leon, with a consistent pattern of failures and advisories related to chassis and structural integrity. The most recent test on 18 June 2026 resulted in a pass, but it followed a failure just one day prior involving the offside front anti-roll bar linkage. The record shows a persistent trend of component degradation, specifically regarding shock absorber oil misting, coil spring corrosion, and exhaust mounting defects, which have appeared across multiple testing cycles between 2023 and 2026. The vehicle has covered 102,791 miles over its approximately 17-year lifespan, representing an average annual accumulation of roughly 6,047 miles. This relatively low annual mileage is consistent with light usage, yet the MOT history reveals that even with lower frequency of road use, specific components such as the suspension bushes, ball joints, and exhaust mountings have required attention. This usage pattern suggests that while the drivetrain may have seen less wear than a high-mileage equivalent, the vehicle has been subject to age-related degradation of rubber seals and metal components. Prospective buyers should pay close attention to the rear suspension and exhaust assembly during a physical inspection and test drive. The record indicates a long-term issue with light oil misting on both nearside and offside rear shock absorbers, as well as repeated advisories regarding a rusty rear exhaust and defective central exhaust mountings. On a test drive, listen for any knocking or clunking sounds from the rear when traversing uneven surfaces, which could indicate that the shock absorbers or exhaust mountings are nearing the end of their functional life. Additionally, check for any excessive vibration or rattling from the underside of the car, particularly during acceleration or when driving over bumps, which may stem from the noted exhaust mounting issues. The front suspension also requires scrutiny due to repeated major failures involving anti-roll bar linkage ball joint dust covers and nearside front suspension arm ball joints. While these specific items were addressed to pass the June 2026 test, the history of ingress of dirt into these components suggests that other suspension linkages may be nearing a similar state of wear. During the test drive, pay close attention to steering precision and listen for any rhythmic clicking or popping sounds when turning the steering wheel at low speeds, as these can be symptoms of failing ball joints or linkage components. Finally, verify the current condition of the tyres, as previous tests have flagged them being worn close to the legal limit.
