2021 SEAT Leon FR Sport TSI EVO 1.5L Petrol · ST21 ONH

The 2021 SEAT Leon currently holds a valid MOT following a pass on 2026-06-05, though the maintenance trend is worsening. The vehicle failed the previous day on 2026-06-04 for severely worn rear brake discs, thin brake pads, and front tyre wear, which were evidently rectified to achieve the subsequent pass. The tester flagged an advisory for light oil misting on the offside front shock absorber during the latest test, pointing to a developing suspension fault. Rectifying brake and tyre failures right before a retest suggests the previous owner allowed critical safety components to degrade to the point of legal failure rather than replacing them proactively. Accumulating 66,356 miles on a 2021 vehicle equates to roughly 13,271 miles annually, a high mileage for its age that accelerates wear on consumables and drivetrain components. The MOT records reveal a particularly rapid mileage accumulation over the last year. Covering 14,522 miles between the June 2025 test at 51,834 miles and the June 2026 test at 66,356 miles, this rate of use heavily explains the recent brake and tyre degradation. The earlier period shows more moderate use, adding 14,838 miles between June 2024 and June 2025, but the recent spike in driving has clearly taken its toll on the braking system. A physical inspection must thoroughly assess the front suspension and wheel alignment. The repeated failure for inner edge wear on both front tyres strongly suggests tracking is out of specification or suspension components are worn, as this is not simple consumable wear. The offside front shock absorber oil misting requires close scrutiny; while currently an advisory, a failing damper will compromise structural integrity and ride quality, potentially accelerating uneven tyre wear. Examine the condition of the rear brake discs and pads, as the tester flagged them as significantly worn just before the recent pass, implying they were replaced, but verifying the quality of this repair is essential. Check the front brake discs for pitting and scoring, which can persist even with new pads if the surface was not properly skimmed or replaced.
