2018 BMW X3 3.0L Petrol · LP68 ONH

The most recent MOT, carried out on 25 February 2026, was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions standards. However, the MOT record over the past five years shows a pattern of recurring rear‑tyre concerns and a once‑off major failure of the tyre pressure monitoring system (TPMS). While the vehicle has cleared each subsequent test after remedial action, the frequency of advisories and a major tyre failure in October 2024 suggest that tyre condition has been a persistent issue rather than an improving trend. At eight years old the X3 has logged 72,320 miles, averaging just over 9,000 miles per annum. This level of annual mileage is typical for a family SUV and does not, on its own, raise red flags about accelerated wear. There are no evident large mileage gaps that would imply prolonged periods of inactivity, but the modest usage does mean that components such as the suspension bushes, engine mounts and drivetrain bearings may have experienced less wear than a high‑mileage counterpart, while age‑related degradation could be more pronounced. Prospective buyers should give particular attention to the rear tyre set. Inspect both sidewalls for cuts, bulges or cracking and measure tread depth across the centre and edges, ensuring a minimum of 1.6 mm remains and that the wear pattern is even. A cut that reaches the ply, as noted in the 2024 failure, typically indicates a compromised structural integrity that could lead to a sudden deflation; any similar damage now would warrant immediate replacement. Verify that the TPMS sensors are operational by checking that the dashboard indicator illuminates briefly on start‑up and then goes out, and confirm that the system reads the correct pressures when the tyres are inflated to the manufacturer’s specification. During a test drive listen for any thumping or vibration that may indicate a damaged tyre or wheel imbalance, and feel for pull or wandering that could signal misalignment resulting from previous tyre issues. Beyond the tyre focus, the vehicle’s age dictates a thorough inspection of time‑sensitive items. Examine the 12‑volt battery for signs of sulphation, check the electrolyte level if it is a conventional lead‑acid type, and assess the cranking voltage; a battery older than four years often benefits from a load test. Inspect the brake discs and pads for surface rust, glazing or uneven wear, especially after the vehicle has been stationary for extended periods. Look for corrosion on the chassis, particularly around the wheel arches and underbody, and ensure that all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – are topped up and that the fluids are clear, not discoloured or contaminated, as many manufacturers recommend fluid changes on a calendar basis irrespective of mileage. A review of the service book for regular oil changes, filter replacements and any recorded suspension or steering component servicing will give further confidence in the overall mechanical health before committing to purchase.
