2004 BMW Z4 3.0L Petrol · KA04 LLU

The vehicle most recently passed its MOT on 26 May 2026 with no defects recorded. Looking at the broader history, the maintenance trend appears stable and generally positive, with several consecutive clean passes in recent years. While there were minor advisories regarding the exhaust system and brake pipes in earlier tests, the absence of these issues in the most recent inspections suggests that necessary remedial work has been carried out or the components have remained within acceptable limits. With a recorded mileage of 111,488 miles over a twenty-two year period, the vehicle has averaged approximately 5,068 miles per year. This is considered low usage for a car of this vintage. While this suggests reduced wear on the engine internals and drivetrain components, low annual mileage often indicates periods of standing. Such usage patterns can lead to specific degradation issues that differ from high-mileage wear, particularly regarding rubber components and fluid chemistry. Despite the clean recent record, a prospective buyer should investigate the historical advisories. The previous mention of a corroded nearside rear brake pipe suggests a susceptibility to rust in the chassis area; you should inspect the underbody for surface corrosion and ensure the brake lines are secure and free from pitting. Additionally, the history of a noisy exhaust and a middle-section blow warrants a careful listen during the test drive for any abnormal drones or leaks, which could indicate the onset of further exhaust manifold or silencer degradation. Given the vehicle's age and low usage, physical inspection must focus on time-based deterioration. Check the tyre sidewalls for fine cracking or perishing, as tyres often age out before they wear out. Inspect the brake discs for heavy corrosion or evidence of binding calipers resulting from inactivity. It is also critical to verify the service history for calendar-based fluid changes, as engine oil and brake fluid degrade over time regardless of mileage. Finally, test the 12V battery health and check for any signs of fluid leaks around the engine seals, which can harden and shrink when a vehicle is not driven frequently.
