2009 BMW 520 2.0L Diesel · NA59 HDK

The most recent MOT inspection conducted on 7 April 2026 resulted in a pass, but the vehicle shows a concerning trend of increasing advisory items compared to previous years. While the vehicle has maintained a consistent pass record since 2019, the recent accumulation of defects suggests a period of accelerating mechanical wear. The transition from a clean record in 2024 to multiple advisories in 2025 and 2026 indicates that several components are reaching the end of their serviceable life simultaneously. This pattern suggests that while the vehicle is currently roadworthy, it is entering a phase of more frequent and potentially costly maintenance requirements. With 186,065 miles recorded over approximately 17 years, the vehicle has averaged roughly 10,945 miles per year. This is considered typical annual usage for a premium executive saloon of this age, suggesting the car has been used regularly rather than sitting idle for long periods. However, this mileage level places significant cumulative stress on the drivetrain, suspension, and steering systems. At this stage of its life cycle, high-mileage components such as the steering rack, suspension bushings, and brake lines are subject to advanced fatigue, and the buyer should expect that many wear-and-tear items will require replacement in the near future to maintain safe handling characteristics. A primary area of concern is the recurring advisory regarding play in the steering rack inner joints, which has been noted in multiple tests since 2023. This indicates progressive wear in the steering mechanism that could lead to vague steering response or a wandering sensation on the motorway. During a test drive, listen for any knocking or clunking noises when turning the wheel at low speeds or when driving over uneven surfaces. Additionally, the recent advisory for a distorted offside front road wheel is significant; a bent rim can cause high-speed vibrations through the steering wheel and may lead to uneven tyre wear or even tyre failure if the structural integrity is compromised. You should also inspect the tyres closely, as the recent advisories for cracking and perishing on both front tyres suggest the rubber is ageing and losing its elasticity, which increases the risk of a blowout. The suspension and braking systems also require careful scrutiny. The history of worn lower suspension arm bushes indicates that the vehicle's ability to maintain geometry is degrading, which can cause the car to pull to one side or result in unpredictable handling during cornering. Furthermore, the previous advisories regarding deteriorated rear brake hoses mean you must check for any signs of swelling, cracking, or weeping fluid near the calipers, as failing hoses can lead to a spongy brake pedal or sudden loss of braking pressure. Ensure you check the service history for evidence of regular fluid changes, specifically brake fluid and coolant, as these are time-sensitive rather than just mileage-sensitive. Given the age and mileage, a thorough inspection of the underbody for structural corrosion and the engine bay for oil leaks is essential before proceeding with a purchase.
