2004 BMW Z4 2.5L Petrol · KU04 LWB

The vehicle currently holds a roadworthy status following a pass in February 2026 at 183,442 miles. However, the maintenance trend shows signs of instability, as the car failed the test on the same day due to an inoperative engine malfunction indicator lamp and an insecure rear suspension component. While these faults were rectified to achieve the subsequent pass, the presence of a mechanical-related failure suggests that the vehicle may be reacting to MOT requirements rather than following a preventative maintenance schedule. At 183,442 miles over 22 years, the BMW has averaged approximately 8,338 miles per year, which aligns with typical usage for an older roadster. The data shows a consistent accumulation of mileage, with 8,900 miles recorded between December 2022 and February 2025, and another 11,160 miles covered between February 2025 and February 2026. This recent spike indicates the car has not sat idle for long periods, but the high mileage places significant stress on aging rubber components and cooling systems inherent to this age of BMW machinery. A buyer must conduct a thorough inspection of the rear suspension assembly, as the February 2026 failure for an insecure component indicates potential wear in bushings or mounting bolts. The braking system requires close attention; the 2025 test flagged a nearside front binding brake and thin pads on both rear axles, suggesting the calipers may be seizing or the service intervals are fully worn. Given the recent failure related to the engine management system, a diagnostic scan should be performed to ensure no hidden fault codes remain that were simply cleared for the MOT test.
