2020 BMW 730 3.0L Diesel · L44 JLD

The most recent MOT on 2026-05-25 recorded a single defect: a severely deteriorated offside front outer drive shaft joint constant velocity (CV) boot. This issue was first noted in the 2025-06-12 MOT, indicating a recurring mechanical concern. The CV boot’s condition suggests potential exposure of internal components to dirt and moisture, which could lead to premature joint failure if unaddressed. The 2025 MOT also highlighted minor wear on both front lower suspension arm pins or bushes, though these were deemed non-critical as they did not cause excessive movement. No other defects were recorded in the 2024-2022 MOTs, suggesting a generally stable condition prior to 2025. However, the repeated CV boot issue over two consecutive MOT cycles points to a persistent risk, likely linked to either inadequate repair or ongoing wear. The vehicle’s mileage of 96,669 miles over 10 years equates to roughly 9,667 miles per year, which aligns with typical usage for its age. This suggests neither extreme under-use nor heavy wear from high mileage. However, the recurrence of the CV boot defect implies localized stress or maintenance oversight, rather than general deterioration from age. The trend indicates a stable overall condition, with no new critical defects beyond the CV boot and suspension bushing wear.
