2021 SEAT Leon SE Dynamic TSI EVO 1.0L Petrol · DF70 WBZ

The latest MOT test on 30 July 2026 resulted in a pass, but only after an initial failure the previous day for a dangerous front tyre defect and a major reversing lamp switch issue. The advisory history shows a clear trend of rear tyre perishing, which has been noted across both the failed and subsequent passed tests, indicating a progressive deterioration of the rubber due to age rather than mileage. While the immediate failures were addressed, the recurrence of tyre advisories suggests that the vehicle’s maintenance has been reactive rather than preventative, and the overall trend is stable but with emerging wear-related concerns. At 46,334 miles over five years, the annual mileage of approximately 9,267 miles is typical for a vehicle of this age, suggesting consistent rather than excessive or sporadic use. This moderate usage rate implies that mechanical wear on consumables such as brakes, suspension bushes, and drivetrain components should be in line with expectations for a car of this age, without the accelerated degradation seen in high-mileage examples. However, the mileage does not rule out the possibility of periods of inactivity, which can introduce its own issues, such as fluid degradation or corrosion. The most pressing issue is the condition of the tyres, with both rear tyres flagged for cracking or perishing, a common age-related problem that compromises grip and increases the risk of a blowout. On inspection, check the sidewalls and tread for deep cracks, bulges, or exposed cords, and listen for a rhythmic thumping noise on the test drive, which could indicate internal tyre damage. The front tyre failure due to exposed ply or cords highlights the importance of verifying that all tyres, including the spare, are in sound condition and have been replaced since the last MOT. Additionally, the reversing lamp switch failure, though now resolved, warrants a test of all lighting functions to ensure no further electrical gremlins remain. Given the vehicle’s age, also scrutinise the 12V battery health, as five-year-old units often approach the end of their serviceable life, particularly if the car has seen short journeys or extended periods of inactivity. Check for corrosion on the battery terminals and signs of slow cranking. Inspect the brake discs for surface corrosion or uneven wear, which can occur if the car has stood for long periods, and listen for binding or dragging from the calipers. Finally, verify the service history to confirm that time-based fluid changes, such as coolant and brake fluid, have been carried out, as these degrade regardless of mileage and are critical to long-term reliability.
