2009 SEAT Leon Ecomotive S TDI 1.9L Heavy oil · GRZ 2048

Two MOT failures appear in the record – one in April 2019 and another on the same day as a pass in July 2023 – yet neither entry lists any defects. The absence of documented fault codes means the precise cause of those failures is unknown, leaving a small but notable uncertainty about any latent issue that may have prompted the re‑test. The most recent test on 16 November 2024 passed without comment, indicating that at that point the vehicle met the statutory requirements, but the earlier unexplained failures should be a focal point for any pre‑purchase inspection. At 154,057 mi the car averages roughly 9,000 mi per year over its 17‑year life, a mileage rate that sits squarely within normal usage for a family hatchback of this age. The MOT chronology shows regular annual testing with no extended gaps, suggesting the vehicle has been kept on the road consistently rather than sitting idle for long periods. There is no evidence of a sudden mileage surge that would point to accelerated wear on high‑stress components such as the clutch, gearbox or engine bearings. Because the MOT records do not highlight any specific component failures, the buyer’s inspection should concentrate on the systems most commonly implicated in unexplained re‑tests for diesel‑powered small cars. A road‑test should include listening for any irregular clatter from the front suspension or steering rack, feeling for looseness or judder in the steering column, and checking for uneven braking feel or pulsation that could indicate hidden disc or caliper wear. A visual inspection under the bonnet should verify the condition of the intercooler hoses, fuel lines and the exhaust manifold for signs of cracking, corrosion or oil staining, while a brief idle and modest acceleration run can reveal whether the engine emits excessive smoke or a rough idle that might have triggered an emissions‑related failure. Given the lack of recorded defects, the prudent course is to request a full mechanical inspection by a qualified technician who can perform a detailed emissions test, brake pressure check and suspension diagnostics. Confirm that all safety‑critical items – tyre tread depth, wheel bearing play, and the integrity of the seat‑belt pretensioners – are within specification, and ensure there are no hidden leaks or corrosion that could have caused the earlier MOT failures. Only after these checks can a confident assessment of the car’s roadworthiness be made.
