2004 BMW X5 4.8L Petrol · SB 110

Corrosion on the braking system and uneven tyre wear represent the primary mechanical concerns for this vehicle, as evidenced by the most recent MOT pass on 10 October 2025. While the vehicle has maintained a passing status since at least 2021, there is a recurring pattern of advisories regarding the brake pipes. The latest inspection flagged both the nearside and offside front outer brake pipes for corrosion and being covered in grease or other material, a condition that was also noted in the 2022 test. This indicates a persistent issue with the integrity of the hydraulic lines that requires close monitoring to prevent future failure. The recorded mileage of 97,719 miles over a 22-year period reflects an average annual usage of approximately 4,442 miles. This is significantly lower than the typical UK annual mileage for an SUV of this age. While lower mileage can imply less cumulative wear on the drivetrain and engine, such infrequent use can also lead to the degradation of rubber components and the accumulation of moisture or debris in hard-to-reach areas, which may correlate with the observed corrosion on the brake lines. A prospective buyer should pay particular attention to the braking system and suspension geometry during a test drive. Given the advisories for corroded brake pipes, it is essential to check for any changes in brake pedal feel, such as a spongy or soft sensation, which could indicate air or fluid ingress due to compromised lines. Additionally, the 2025 advisory regarding both rear tyres wearing on the inner edges suggests a potential issue with rear suspension alignment or worn suspension bushes. During the test drive, listen for any knocking or clunking noises when traversing uneven surfaces and check for any pulling to one side under braking or during straight-line driving. The history of thin rear brake pads in 2023 also necessitates a verification of current pad and disc thickness. Ensure that the braking performance is consistent and that there is no excessive vibration or judder through the pedal when applying the brakes at speed. Because the brake pipes were noted as being covered in grease or other material, a physical inspection of the underbody is advised to determine if this is a deliberate attempt to mask corrosion or if it is simply a result of previous lubrication efforts.
