2018 BMW X4 XDRIVE20D M Sport Auto 2.0L Heavy oil · D3 KGD

The most recent MOT, carried out on 6 June 2026, was passed with no recorded defects, and the two preceding tests in June 2024 and February 2023 also returned clean passes. This consistent absence of advisory or failure items indicates a stable maintenance pattern; there is no evidence of deteriorating condition or recurring fault that would suggest a worsening trend. At 71 618 miles the X4 is eight years old, giving an average annual mileage of roughly 8 950 miles. This figure sits comfortably within the normal UK usage envelope for a premium SUV and does not point to either unusually low mileage, which could mask long periods of inactivity, nor excessive mileage that would accelerate wear on major components. The mileage progression appears steady, implying that wear on consumables such as brake pads, tyres and suspension elements will be in line with what is expected for a vehicle of this age and class. Given the clean MOT history, the buyer should focus on age‑related inspections. Examine the tyre sidewalls for cracking, dry rot or any signs of perishing, and verify that tread depth remains above the legal minimum and is even across the set, as uneven wear can hint at alignment or suspension issues. Inspect the brake discs for surface corrosion, scoring or excessive rust, and check the pad thickness; any binding calipers will often be evident as uneven disc wear or a shudder when applying the brakes. The battery, now approaching ten years, should be load‑tested and its terminals inspected for corrosion, while the 12 V system voltage should be measured to confirm it holds charge. Verify that the service book contains regular oil changes, timing‑chain or belt service, and that the all‑wheel‑drive differentials have had their fluid refreshed according to BMW’s interval schedule, as fluid degradation can lead to wear in the XDrive system. During a test drive, listen for any clunking or squeaking from the front and rear suspension, which may indicate worn bushings, ball joints or coil‑spring mounts. Pay attention to steering feedback; a vague wander or vibration could be a sign of worn tie‑rod ends or a developing CV joint issue. Apply the brakes firmly at moderate speed and note any pulsation, noise or pulling to one side, which would point to disc warping or uneven pad wear. Finally, observe the dashboard for any warning lamps, particularly those related to engine, emissions or traction control, and watch for excessive exhaust smoke, which could reveal underlying engine or diesel particulate filter concerns. These checks will give a comprehensive picture of the vehicle’s mechanical soundness beyond the clean MOT record.
