2015 Land Rover Range Rover Sport 3.0L Diesel · BX65 ACU

The defining mechanical story on this Range Rover Sport is a generally sound roadworthiness record punctuated by an airbag warning lamp failure in late 2024 and a small cluster of under-body rubber deterioration advisories that emerged at the most recent pass on 7 October 2025. It has passed four of its last five recorded tests with no defects, and the single failure was promptly rectified rather than allowed to compound, which suggests the underlying structural and safety-critical systems remain in healthy order. That said, the appearance of deteriorated ball joint dust covers and a perished CV joint boot on the latest test warrants close inspection, as both rubber components shield critical moving parts from grit and moisture ingress, and their failure accelerates wear of the ball joints and CV internals if left unattended. Covering around 7,400 miles per year across its eleven-year life, this vehicle sits broadly in line with typical usage for its age, and the MOT record shows no extended testing gaps or unusually rapid mileage jumps that would hint at inconsistent use or clock irregularities. Mechanical implication of this steady accumulation rate is that consumables such as brake pads, discs, tyres and the air suspension components characteristic of this model will have experienced proportionate wear rather than the accelerated degradation seen on high-mileage examples. Conversely, it has not covered the very low annual mileages that can bring their own problems around seized callipers, perished air springs from prolonged standing, or stale fluids. The driving pattern appears consistent with mixed private use including motorway mileage, which is generally kinder to the drivetrain than stop-start urban work. For a prospective buyer, the under-ball-joint and CV boot advisories from October 2025 demand particular attention. On the test drive, listen for any clonking or knocking from the front suspension, particularly over speed humps and uneven road surfaces, as this can indicate that grit has already entered the worn ball joint boots and begun destroying the ball joints themselves. The perished offside rear outer CV boot is a known failure point on these vehicles; a torn boot allows grease to escape and contamination to enter, so listen for a rhythmic clicking or knocking from the rear when turning at low speed, and inspect the inner wheel arch area for fresh grease fling. Both boots are relatively inexpensive to replace in isolation, but rebuilding the joints after contamination damage becomes substantially more costly. Beyond the flagged items, an SRS warning lamp fault appearing and then clearing on the subsequent test is a pattern worth investigating before purchase, as intermittent airbag system faults can stem from corroded connector pins beneath the seats, a failing clock spring in the steering column, or low battery voltage during testing. It is worth requesting evidence that the fault was properly diagnosed and rectified rather than simply cleared from the system memory. Given this vehicle's air suspension architecture, a thorough test should also include listening for any compressor overrun at start up, observing whether the vehicle settles overnight and rises promptly on first drive, and checking for any warning messages on the infotainment screen related to ride height or suspension faults. With the specific advisories addressed and a clean diagnostic read of the airbag system, this Range Rover Sport presents as a fundamentally roadworthy example rather than one requiring immediate major intervention.
