2015 SEAT Leon 1.6L Diesel · DG15 DVL

The vehicle remains roadworthy but the maintenance history shows a worsening trend regarding reactive rather than proactive care. While the most recent test in July 2025 at 209,805 miles passed, it noted a persistent oil leak on the undertray which had also appeared in the 2024 and 2023 tests. This suggests a slow gasket or seal degradation that has not been addressed despite multiple inspections, despite the leak remaining below the MOT failure threshold. At 209,805 miles, this eleven-year-old Leon has covered significant ground, averaging approximately 19,000 miles per year. The mileage accumulation is consistent and rapid, with 14,244 miles logged between the July 2023 and July 2024 tests and another 12,231 miles in the following year. This high usage rate puts extreme strain on the drivetrain and suspension components, which is reflected in the increasing frequency of wear-and-tear defects recorded in the latter three years. A buyer must inspect the braking system thoroughly, as the 2024 test flagged fluctuating offside front service brakes and thin rear pads. Fluctuations often indicate warped discs or sticking calipers, which require replacement rather than simple adjustment. The 2023 record also highlighted multiple tyres reaching the legal limit with uneven wear and structural damage, indicating that the previous owner likely only replaced consumables when they faced imminent failure. The physical inspection should focus on the source of the recurring oil leak to determine if it is a minor seal or a more significant engine issue. Given the frayed seat belt webbing noted in 2023, the interior should be checked for further material degradation. The high annual mileage also demands a close look at the suspension bushes, shock absorbers, and exhaust system, as these components are nearing the end of their functional life despite not explicitly mentioned in the MOT advisories.
