2017 BMW X4 2.0L Diesel · YB66 UAX

The vehicle currently holds a roadworthy status, following a clean MOT pass on 28 April 2025 at 51,854 miles. This recent result indicates a stable maintenance trend after a period of mechanical instability in early 2024. The transition from multiple failures to a defect-free certificate suggests that previous issues identified by the tester were addressed effectively, returning the vehicle to a compliant standard for road operation. The mileage profile remains low for a nine-year-old vehicle, averaging approximately 5,762 miles per year. The data shows a significant gap of 3,280 miles between February 2023 and February 2024, followed by a more rapid accumulation of 4,332 miles in the subsequent year. While low annual mileage generally reduces wear on the drivetrain and engine components, long periods of standing can sometimes lead to rubber-based components, such as suspension bushes or seals, degrading through age despite the low mileage. A buyer should focus their physical inspection on the specific areas that caused the consecutive failures in February 2024 at 47,491 and 47,522 miles. Although the record does not detail the specific failure reasons, the rapid succession of failures often points to consumable items like brake components, tyre compliance, or exhaust emissions. Inspect the brake discs for uneven wear or pitting and check the suspension arms for perished bushings to ensure the repairs made in 2024 remain robust. Given the vehicle's age, also verify the structural integrity for any signs of corrosion that may not have reached an advisory threshold yet during the last test.
