2015 Land Rover Discovery Luxury HSE SDV6 Auto 3.0L Diesel · SC65 HPK

A pattern of two consecutive failures immediately prior to a pass on 19 August 2025 stands out as the defining mechanical event in this Discovery's recent history, with no defects recorded against any of the three tests. While a clean pass is reassuring, two failures within the same month is unusual and warrants direct enquiry with the seller to establish whether rectification work was carried out between 19 August and the current date, or whether any components were replaced, repaired, or temporarily removed to achieve the pass. The absence of recorded advisories across the most recent and 2024 tests suggests that, on the day of examination, the vehicle was free of tester-noted deterioration, but MOT records only capture what was visible at the time of test and do not constitute a mechanical guarantee. Prior to this cluster, the car passed cleanly in October 2022, indicating that the intervening period may have introduced new wear rather than reflecting a long-standing problem. At 97,149 miles over approximately eleven years, this Discovery has covered around 8,800 miles per year, which is broadly typical for its age and class but skews towards the lower end for a large SUV that often sees motorway and towing use. The mileage gap between the October 2022 test and the July 2024 test implies an accumulation of roughly 7,000 to 8,000 miles per year in that interval, while the absence of a recorded test in 2023 means the precise rate during that window cannot be confirmed from DVSA records alone. Lower annual mileage on a diesel of this vintage can bring its own considerations, particularly around short-trip usage that fails to fully evaporate condensation from the oil and exhaust system, while the higher 2022-to-2024 accumulation suggests the vehicle has been in active service rather than laid up. For a buyer, verifying the continuity of the mileage on the V5C and service documents is worthwhile to ensure no gaps or anomalies exist between recorded readings. Given that the MOT history contains no component-specific advisories, a pre-purchase inspection should focus on the known wear-prone areas of the SDV6 Discovery that commonly surface between tests but may not have been flagged on the day. On a test drive, listen for clonks or knocks from the front suspension over speed humps and uneven surfaces, which would point to worn lower wishbone bushes, anti-roll bar links, or front hub bearings, all of which are common on this platform at this mileage. Check for any pulling under braking, vibration through the steering wheel, or a soft or spongy pedal feel that might indicate warped front brake discs or air ingress into the brake system, and inspect the inner and outer faces of the wheels for brake disc lipping and pad wear. At idle, observe for excessive blue or white smoke from the exhaust, which could suggest turbocharger seal wear, EGR valve fouling, or injector tip leakage on the 3.0 SDV6 unit, and listen for any timing chain rattle on cold start that may indicate stretched guides or tensioner wear. A thorough underside examination is strongly advised for any Discovery of this age, paying particular attention to the front and rear subframes, suspension arms, and brake pipes for any surface corrosion or underbody sealing deterioration that might not have been visible from the standard MOT test position. Inspect the condition of the timing belt service history, as the SDV6 engine requires replacement of the auxiliary drive belt and tensioners at manufacturer-specified intervals, and check that all four injector harness connectors and the intercooler pipework are free from oil staining. During a road test, exercise the transfer box and terrain response modes if possible, ensuring that high and low range engage smoothly and that the air suspension, if fitted, raises and lowers without hesitation or audible pump strain. Finally, verify the operation of the electronic parking brake, central locking, and any infotainment or camera systems, as electrical faults on this generation are frequently reported and would not necessarily be captured in MOT data.
