2017 SEAT Leon 1.6L Diesel · LM17 AAU

The most recent MOT, carried out on 7 May 2025, was passed with no recorded defects, and the preceding two annual tests in April 2024 and April 2023 also returned passes. The only anomaly in the history is a recorded failure on 17 April 2023, although no specific fault was logged. This isolated failure, unaccompanied by any defect notation, suggests either an administrative discrepancy or a minor issue that was rectified before the vehicle was re‑tested. Overall the MOT trend is stable, with three consecutive clean passes indicating that the car has been maintained to a satisfactory standard in recent years. At 55 650 mi the 2017 SEAT Leon averages roughly 6 200 mi per annum, which sits comfortably within the typical UK usage pattern for a nine‑year‑old vehicle. There are no evident periods of unusually high mileage that would accelerate wear on high‑stress components such as the clutch, gearbox or suspension. The relatively modest annual distance also implies that many wear items – tyres, brake pads and discs, and engine oil – are likely to be within their service windows, provided they have been changed at appropriate intervals rather than simply being left to age. For a prospective buyer the primary focus should be on time‑related degradation rather than mileage‑driven wear. Inspect the tyre sidewalls for cracking, dry rot or hardening, especially if the car has spent long spells stationary; uneven tread wear could reveal mis‑alignment or worn suspension bushes. Examine the suspension for any play in the front lower wishbones, rear trailing arms and rubber bushings, and listen for clunks over bumps during a short test drive. Verify that the brake discs are free of deep rust spots or scoring and that the pads have sufficient thickness; any shudder or pulsation when applying the brakes may indicate warped discs or glazed pads. Check the 12‑volt battery for terminal corrosion and test its cranking voltage, as a nine‑year‑old unit can lose capacity even with modest use. Finally, confirm that all service book entries are present and that coolant, brake fluid and gearbox oil have been replaced in line with the manufacturer’s calendar schedule, since fluids degrade with age irrespective of distance travelled. Pay particular attention to any signs of corrosion on the chassis, especially around the wheel arches, under‑body and suspension mounting points, which can develop when a vehicle is frequently parked for extended periods. Inspect the exhaust system for rust perforation or loose mounts that could cause excess vibration. Ensure that all lights, wipers and electronic aids operate correctly, as ageing wiring can develop intermittent faults. A thorough visual and audible inspection, coupled with a short road test, should reveal whether the Leon remains mechanically sound and ready for continued ownership.
