2008 BMW Z4 2.0L Petrol · N23 GCB

The most recent MOT on 2026-05-22 recorded several minor defects, including direction indicators flashing too rapidly, a non-functional offside registration plate lamp, nearside rear tyre wear close to the legal limit, and corroded rear coil springs. These issues were also present in the prior MOT on 2026-05-16, which resulted in a failure. The recurring nature of these defects suggests unresolved underlying problems, particularly with lighting systems, tyre condition, and corrosion in suspension components. A pattern of corrosion in suspension parts, such as coil springs and suspension arms, has persisted across multiple MOTs since 2024. While some corrosion was noted as “not seriously weakened,” the repeated occurrence indicates potential exposure to harsh environments or inadequate maintenance. Tyre wear near the legal limit has also recurred, raising concerns about tread depth consistency and possible misalignment or suspension issues. The trend shows mixed stability. A clean MOT in 2025 provided a temporary reprieve, but subsequent tests reveal re-emerging issues. The 2026 MOT included the same tyre and corrosion defects as the 2026 failed test, suggesting these problems have not been fully resolved. However, the absence of severe failures like exhaust smoke or ABS faults in the latest test indicates some improvement in critical systems.
