The most recent MOT test passed on 25 November 2025, but it introduced critical advisories regarding tyre wear on both the front and rear axles. While the vehicle showed a clean record through much of 2024, including a successful rectification of a tyre pressure monitoring system failure in August 2024, the recent advisories indicate a declining trend in the maintenance of consumable components. The transition from a defect-free status to multiple tyre advisories suggests that the vehicle is entering a phase where significant wear-and-tear maintenance will be required shortly. With 54,831 miles recorded over approximately five years, the vehicle has averaged roughly 11,000 miles per year. This represents typical, moderate usage for a diesel-powered premium SUV and is unlikely to have caused premature mechanical fatigue to the drivetrain or engine. The mileage is consistent with a vehicle that is used regularly for commuting or family duties rather than one that has been neglected through long periods of standing or subjected to heavy commercial use. Consequently, the mechanical integrity of the mild-hybrid system and the diesel engine should be theoretically sound, provided the service intervals have been strictly adhered to. The primary mechanical concern for a buyer is the uneven tyre wear noted in the latest advisory. The fact that tyres are worn on the edges suggests a potential issue with wheel alignment, camber, or suspension component wear, such as perished bushes or worn ball joints. During your test drive, you must check for any steering pull, vibration through the steering wheel, or rhythmic humming noises from the road surface. It is also essential to verify that the tyre pressure monitoring system, which caused a failure in 2024, is now functioning correctly without intermittent dashboard warnings. Given the proximity to the legal limit, a complete replacement of the tyres should be factored into your immediate acquisition costs. In addition to the tyres, the uneven wear pattern warrants a thorough inspection of the suspension and braking systems. Inspect the brake discs for evenness and listen for any squealing or grinding that might indicate worn pads or binding calipers. A pulsating brake pedal during deceleration could indicate warped discs, which may be related to the same driving patterns causing the uneven tyre wear. Finally, ensure the service history is documented to confirm that all fluid changes and inspections have been carried out according to the manufacturer's schedule, as this is vital for maintaining the long-term reliability of the XDRIVE system and the turbocharger.
