2004 BMW Z4 3.0L Petrol · MT54 AFJ

The 2004 BMW Z4’s most recent MOT on 2023-09-28 at 120,944 miles recorded a failure with no defects listed, indicating potential unresolved issues. Prior tests show a pattern of repeated failures and passes at identical mileages, such as the 2022-10-12 pass and 2022-10-11 failure both at 119,528 miles, suggesting inconsistent testing or unresolved mechanical faults. The lack of recorded defects in these tests complicates diagnosis, but the frequency of failures implies ongoing maintenance challenges. No recent tests post-2023-09-28 are available, leaving the vehicle’s current roadworthiness unverified. The vehicle’s mileage of 120,944 miles over 22 years equates to approximately 5,497 miles annually, significantly below average for its age. This low usage could indicate prolonged periods of inactivity, increasing risks of fluid degradation, corrosion, and component stiffness. Notable gaps exist between tests, such as the 22-month interval between the 2021-12-08 pass at 114,204 miles and the 2023-09-28 failure, raising concerns about maintenance consistency. While the MOT history is sparse, the absence of defects in passes does not confirm mechanical soundness, as critical issues may have been overlooked. A buyer should prioritise inspecting the suspension system for worn bushes or coil springs, as low mileage often masks hidden wear from inactivity. Brake components, including calipers and discs, require scrutiny for binding or corrosion, given the repeated failures. Structural integrity checks are vital to detect rust, particularly in the underbody and body seams, which can worsen during long-term storage. The exhaust system and engine bay should also be examined for leaks or deterioration, as infrequent use may have led to neglected servicing. Without recent MOT data, a professional inspection is essential to confirm the vehicle’s condition.
