2018 BMW X1 2.0L Petrol · NA18 AAJ

The most recent MOT on 20 July 2026 was passed, but it carried an advisory that the off‑side rear tyre shows slight damage, cracking or perishing. This mirrors the advisory recorded in the previous year and follows a pattern that began in 2022 when all four tyres were flagged for similar early‑life degradation. While the vehicle has consistently passed the safety items, the recurrence of tyre advisories indicates a gradual worsening of the tyre condition rather than an improvement, suggesting that the rubber has been ageing faster than the tread wear would predict. At eight years old the odometer reads 29 666 miles, which works out to roughly 3 700 miles per annum – well below the UK average for a family SUV. Such low utilisation often points to periods of limited use or prolonged storage, which can be benign for drivetrain components but accelerates tyre perishing, battery sulphation and fluid breakdown. The modest mileage means that wear items such as clutch plates, engine bearings and suspension bushings are likely to be in good shape, yet the calendar age of the vehicle imposes its own set of maintenance requirements. Prospective buyers should give the tyre set the highest priority. All four tyres have been flagged for cracking or perishing over the last four years, a clear sign that the rubber compound is deteriorating despite limited tread loss. Inspect each tyre for sidewall cracks, dry rot, and any bulges; measure tread depth to ensure it remains above 1.6 mm on all corners. During a test drive listen for a low‑frequency hum or feel a subtle vibration that may indicate uneven wear or a developing separation of the tyre carcass. If any tyre shows more than minimal cracking, replacement is advisable sooner rather than later, and a professional alignment check should follow to prevent premature wear on the new set. Beyond the tyres, the vehicle’s age warrants a thorough review of time‑based items. Verify the health of the 12 V battery, especially if the car has spent long periods idle, by checking voltage under load and ensuring the terminals are clean. Examine the brake discs for surface rust or glazing and confirm that the calipers move freely without binding; any pulsation in the pedal or shudder at higher speeds can indicate disc wear or uneven pad deposition. Inspect all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for colour, level and any signs of contamination, as fluids can degrade even when mileage is low. Finally, request the full service book to confirm that scheduled oil changes, filter replacements and any timing‑chain inspections have been logged; a well‑documented service history will give confidence that the vehicle’s mechanical heart has been looked after despite its modest mileage.
