2015 BMW 640 3.0L Diesel · L48 BAT

A consistent record of roadworthiness has recently been interrupted by the emergence of suspension wear, as evidenced by the pass on 14 April 2026 which flagged worn pins or bushes in the front lower suspension arms on both sides. Prior to this, the vehicle maintained a clean testing history with no defects or advisories recorded across four consecutive annual tests dating back to March 2022. This shift suggests the onset of typical component degradation after a period of stability. The recorded mileage of 86,866 miles over an eleven-year period represents an average annual accumulation of approximately 7,900 miles. This usage pattern is typical for a vehicle of this class and age, implying that mechanical wear on the drivetrain, braking system, and chassis components has progressed at a standard rate. There are no significant gaps in the testing history or abrupt spikes in mileage that would suggest periods of prolonged inactivity or excessive heavy-duty use. Attention must be directed toward the front suspension geometry and linkage integrity during a physical inspection. The advisory regarding the front lower suspension arm bushes indicates that the rubber components are beginning to perish or compress, which can compromise steering precision and tyre wear. During a test drive, listen for audible knocks or clunks when traversing speed bumps or uneven road surfaces, and feel for any excessive vibration or vagueness in the steering wheel during cornering. Further evaluation should include a check for steering pull or instability during hard braking and acceleration, as worn suspension bushes often manifest as a shifting sensation in the front end under longitudinal load. While the rest of the MOT history is clear of structural or braking defects, the current status of the suspension arms suggests they are approaching the end of their functional lifespan and will likely require replacement to prevent further deterioration of the vehicle's handling characteristics.
