2006 BMW 630 3.0L Petrol · X21 DCJ

The vehicle is currently roadworthy but the maintenance history reveals a concerning pattern of reactive rather than proactive care. While the most recent test in August 2025 at 92,238 miles passed, the record shows a persistent engine oil leak that has appeared in every annual test back to 2022. This indicates a long-term defect that has not been rectified, suggesting the owner is only performing the minimum work required to pass the MOT de-certification rather than addressing the mechanical root cause. At twenty years old, the recorded mileage of 92,238 miles is significantly low, averaging approximately 4,600 miles per year. This low-use profile often leads to age-related degradation of rubber components rather than mechanical wear from distance. Between August 2023 and August 2024, the car covered only 3,363 miles, yet it failed the August 2024 test due to both rear tyres having exposed ply and cords. This suggests that despite the low mileage, basic safety-critical consumables were neglected until they reached a critical failure point. A buyer must conduct a thorough inspection of the engine bay to determine the source of the chronic oil leak, focusing on valve cover gaskets and oil filter housings which are common failure points on this engine. The recurring advisories for uneven tyre wear in 2022 and 2023 point to potential alignment issues or worn suspension bushings that remain unaddressed. Given the vehicle's age and low mileage, a physical inspection should also check for cracks in rubber hoses and perished brake lines, as these components degrade over time regardless of the few miles driven.
