2005 BMW Z4 2.5L Petrol · OU55 PSX

The 2025‑04‑29 MOT shows the 2005 BMW Z4 passed with no recorded defects at 66,475 mi, indicating that the most recent inspection found nothing outright unsafe. A clear pattern emerges across the last five MOTs: the front anti‑roll‑bar linkage dust cover is repeatedly noted as “severely deteriorated”, and front suspension arm ball‑joint play has been flagged in 2022 and 2023. Tyre condition has also been a recurring concern, with cracking or perishing noted on both front and rear tyres in 2022 and again on the rear tyres in 2024. Brake‑pipe corrosion was first recorded in 2021 and appears again in 2022, though no failure was recorded. The trend is relatively stable – the same dust‑cover and ball‑joint issues persist rather than escalating to outright failures, but the problems have not been resolved and continue to appear each year. Tyre wear and brake‑pipe corrosion have been added to the list, suggesting a modest deterioration in the condition of consumables. Mileage is very low for a 21‑year‑old car – roughly 3,200 mi per year. This could mean the car has been lightly driven, which often reduces wear on major drivetrain components, but it may also indicate long periods of inactivity. Prolonged storage can accelerate corrosion (as seen on the brake pipes) and allow rubber parts to dry out, which aligns with the dust‑cover and tyre issues. What to check first: - Inspect the front anti‑roll‑bar dust covers and associated ball joints for cracks, excessive wear or looseness.
