2006 SEAT Leon 2.0L Diesel · MM06 AEF

The vehicle presents a concerning roadworthiness profile with a worsening trend in mechanical and electrical neglect. While the car passed its most recent test in November 2025 at 112,554 miles, this followed a significant failure just two days prior that revealed critical safety issues including a supplementary restraint system fault, poor parking brake efficiency, and multiple exterior lighting failures. The persistent presence of an oil leak across nearly every inspection since 2014 suggests a reactive maintenance approach where faults are only addressed when they threaten compliance rather than through preventative care. The mileage pattern is characteristically low for a twenty-year-old vehicle, averaging approximately 5,600 miles per year. The record shows a clean period between 2017 and 2020, where no defects were recorded. However, the frequency of failures has increased significantly as the vehicle crossed 100,000 miles. The gap between the 2024 and 2025 tests shows only 2,845 miles of travel, which may have contributed to the accelerated degradation of rubber-based components despite the low annual mileage. A buyer must conduct a thorough inspection of the braking system and chassis components. The history shows recurring issues with corroded brake pipes and pitted discs, alongside a specific failure of the parking brake in late 2025. Corrosion was noted on the rear lower suspension arms in 2024, and the rear exhaust box was flagged for corrosion, suggesting the underbody is susceptible to environmental damage. Furthermore, the repeated failure of the engine management light and the SRS warning lamp indicates underlying electrical or sensor faults that have not been definitively resolved.
