2015 SEAT Leon 2.0L Diesel · OY65 BHO

The most recent DVSA examination dated 1 September 2026 resulted in a pass, although three advisories were recorded against the rear axle, namely corroded coil springs on both sides, brake discs worn and pitted though not seriously weakened, and tyres worn close to the legal limit and on edge both sides. Looking at the broader MOT history, the vehicle has demonstrated a generally consistent pass rate over the past five years, with the 2021 failure relating to an airbag warning lamp fault being the only significant deviation and appearing to have been rectified at the subsequent retest. However, the trend in advisory items does suggest progressive deterioration at the rear of the vehicle, as the coil spring corrosion and brake disc surface corrosion advisories first surfaced in 2022, recurred in 2024 on the springs, and have reappeared in 2026 alongside additional tyre wear concerns. This pattern is indicative of components reaching the latter stages of their service life rather than any sudden mechanical concern. With 89,098 miles recorded on an eleven year old SEAT Leon, the vehicle has covered approximately 8,100 miles annually, which sits comfortably within the typical usage bracket for a car of this age and is neither excessively low nor notably high. The mileage progression between tests appears steady and incremental without any sudden large gaps that would suggest long periods of standing, nor any rapid accumulation that would point to sustained high-mileage motorway use. That said, even at average annual mileage the mechanical wear items already manifesting on the rear axle suggest the vehicle is now entering a phase where several consumable and maintenance items are due for renewal. The recurring advisories on the rear coil springs warrant particular attention from a prospective buyer. Coil spring corrosion in this region of the vehicle is a common age-related issue caused by road salt, moisture, and general exposure to the elements, and once surface corrosion is recorded it typically progresses through the cross-section of the spring, ultimately leading to brittleness and possible fracture. On a test drive, listen for any clonking or knocking from the rear suspension over uneven surfaces, and pay attention to whether the rear of the car feels unsettled, floats excessively over bumps, or shows any loss of ride height on one side compared to the other. The pitted and corroded rear brake discs recorded in 2022 and again in 2026 suggest prolonged surface oxidation, which on a road test can manifest as brake pedal shudder under firm application, uneven braking effort, or a grinding sensation if pads have worn into the corroded surface. The tyres being worn close to the legal limit means replacement is imminent and should be factored into purchase negotiations, while the front brake disc corrosion and pad wear advisories from 2021 indicate that, although not raised since, the front braking system should be inspected for pad material thickness and disc lip formation given the higher mileage now recorded. Beyond the documented items, a vehicle of this age and mileage merits a thorough physical inspection regardless of its MOT record. Check all four tyres carefully for sidewall cracking or perishing, as rubber degrades with age irrespective of tread depth, and inspect the inner wheelarches, sill jacking points, brake lines, and underbody mounting areas for any corrosion that an MOT examiner might not necessarily flag in the standard test. Inspect the coolant, brake fluid, and transmission fluid for age-related discolouration, as these should be replaced on a calendar basis regardless of mileage. Examine the 12 volt battery for any signs of swelling, corrosion around the terminals, or intermittent starting behaviour, and consider that an eleven year old original battery is well beyond its expected service life. On the test drive, ensure the engine reaches operating temperature cleanly without excessive smoke from the exhaust, that the clutch biting point is consistent, that the manual or DSG transmission selects all gears smoothly without judder, and that the electronic systems, including the previously flagged airbag warning lamp, are fully illuminated at ignition and extinguish promptly after start-up.
