2015 SEAT Leon 1.6L Diesel · LK15 TBU

The 2015 SEAT Leon’s most recent MOT test on 3 March 2025 at 132,445 miles passed without defects, indicating a stable roadworthiness status at this juncture. However, the preceding records reveal a pattern of recurring minor issues, particularly in the 2023 and 2022 tests, which suggest the vehicle has not been maintained with consistent diligence. The 2023 test highlighted widespread brake disc wear across all four corners, alongside light oil misting on all four suspension dampers—a condition that, while not immediately critical, implies prolonged neglect of fluid top-ups and potential internal wear. The 2022 tests were more concerning, with repeated failures on tyre condition (both nearside front and offside front tyres worn to 2.4mm, nearing the legal limit) and a distorted nearside rear wheel, alongside a non-functioning indicator. These faults indicate a vehicle that has been driven with insufficient attention to consumables and alignment, with no evidence of corrective action between tests. The mileage progression of 132,445 miles over eleven years—approximately 12,000 miles annually—is unusually high for a vehicle of this age, suggesting either intensive use or prolonged periods of inactivity without proper storage. There are no gaps in MOT testing beyond the standard three-year interval, but the consistency of wear-related failures points to a lack of proactive maintenance rather than deliberate deferral. The most rapid accumulation appears between the 2022 and 2023 tests, where mileage jumped from 84,444 to 92,813—a 8,369-mile increase in just over a year—before continuing at a similar rate. This pattern does not align with typical low-mileage preservation but instead reflects a vehicle that has been driven regularly without the corresponding upkeep. A prospective buyer should prioritise an independent inspection of the suspension components, particularly the dampers, which showed consistent oil misting in 2023—a sign of potential internal leakage or degraded seals. The brake discs, while not critically weakened in the latest test, exhibited widespread pitting and scoring in 2023, warranting assessment for uneven wear or glazing that could compromise stopping performance. The nearside rear wheel distortion from 2022 may have been addressed, but the wheel alignment and tyre condition should be rechecked, as the front tyres in that test were dangerously close to the legal limit. Structural integrity should also be scrutinised, especially the nearside front sill, which was noted as damaged or deformed in 2023, as this could indicate underlying corrosion or impact damage. Finally, the electrical system—particularly the nearside rear indicator—must be tested, as its failure in 2022 was not resolved in subsequent tests.
