2015 SEAT Leon SE Technology TDI 1.6L Heavy oil · AEZ 80

A spotless MOT record across the last four years, culminating in a clean pass on 2 December 2025, tells the story of a vehicle that has consistently met the statutory safety and emissions standards. No advisories or failures have been logged, indicating that the major systems – brakes, suspension, steering, lighting and emissions – have remained within acceptable limits throughout the recent testing period. At 123,500 miles for a 2015 model, the car averages just over 11 000 miles per annum, which sits squarely within the normal usage envelope for a diesel‑powered hatchback of this age. The annual testing cadence shows no prolonged gaps, suggesting the vehicle has been kept on the road rather than stored for extended periods. This mileage level typically brings moderate wear to consumables such as brake pads, disc rotors, tyre tread, and suspension bushings, while still leaving ample life in major components like the engine, gearbox and chassis, provided routine maintenance has been observed. When you inspect the car, give particular attention to the front and rear suspension – listen for any clunking or knocking over bumps that could indicate worn control arm bushes or deteriorating shock absorbers. Test the steering for any play or uneven pull, especially at low speeds, which would reveal loosened tie‑rod ends. During a gentle brake application, feel for pedal pulsation or a spongy feel that might betray thinning pads or warped discs, even though none were flagged at MOT. A quick visual check of the exhaust should confirm there is no excessive smoke or rattling, and a brief idle should be smooth, with no unusual rattles that could hint at a loose mounting or impending turbo wear. Given the mileage, the timing belt (or timing chain, depending on the specific TDI variant) will be approaching the service interval recommended by the manufacturer, so a review of the service booklet for the next replacement deadline is prudent. The diesel particulate filter will have accumulated a substantial load of soot; verify that the vehicle completes a regeneration cycle without warning lights, and watch for any lingering exhaust odor that could signal a clogged filter. Finally, examine tyre tread depth and sidewall condition, and ensure the battery is holding charge, as these items are not captured by MOT but are critical to reliable day‑to‑day operation. A thorough test drive that checks for the symptoms outlined above will give you confidence that the car’s mechanical condition matches its clean MOT history.
