2009 SEAT Leon 1.9L Diesel · YP59 YFW

The 2009 SEAT Leon presents a mixed but ultimately improving maintenance picture as of its most recent test. The September 2025 pass at 154,396 miles with zero defects is a strong indicator that the significant corrosion and mechanical wear flagged in 2024 has been addressed. The trend is resolving, moving from a heavily advisory-laden 2024 test back to a clean bill of health, suggesting the last owner invested in remedial work rather than ignoring the issues. The fractured coil spring and binding rear brake that caused the September 2023 failure were also rectified before the 2024 test, confirming a pattern of reactive but effective repairs. Mileage accumulation tells a story of consistent, typical use. The vehicle covered roughly 24,355 miles between September 2024 and September 2025, a notable jump from the 14,246 miles added in the prior year. This acceleration is not alarming for a 17-year-old car averaging around 9,000 miles annually, but it does mean the current high mileage is the result of recent, sustained use rather than long-term low-mileage storage. The MOT record is complete with no gaps, providing a reliable chronological view of the vehicle's condition. The 2024 test revealed extensive surface corrosion across the rear sub-frame, suspension arms, chassis legs, and sills, all noted as not seriously weakened but clearly advanced for a car of this age. A prospective buyer must physically inspect these underside areas with a torch and probe to confirm the corrosion is superficial and not structural. The advisory regarding the offside front anti-roll bar linkage ball joint having slight play and the rear suspension bushes showing wear points to a front end that may still require attention despite the clean 2025 test. Check for clunking over uneven surfaces and uneven tyre wear. The history of binding rear brakes and a fractured front coil spring in 2023, combined with the deteriorated CV boot noted in 2024, indicates the drivetrain and braking system have experienced stress. During a test drive, listen for clicking from the offside front driveshaft during tight turns and test the handbrake on a slope to ensure the rear calipers release fully. The persistent oil leak advisory from 2024, though deemed non-excessive, warrants a close inspection of the engine and gearbox mounts for fresh wetness, as slow leaks can escalate with the vehicle's current high mileage.
