2009 BMW 525 2.5L Petrol · YN59 AVO

The vehicle remains roadworthy, though the maintenance history reveals a trend of escalating component wear and deferred attention. While the most recent test in August 2025 at 108,449 miles passed without mechanical advisories, the inspection was hampered by a child seat preventing a full belt check. The previous years show a consistent pattern of developing faults across the suspension and braking systems, suggesting that components are addressed only when they approach an MOT failure threshold rather than through preventative maintenance. At 108,449 miles over 17 years, the car averages approximately 6,380 miles per year, which is considered low-to-moderate usage. The mileage progression shows consistent use with roughly 8,000 to 14,000 miles driven between annual tests from 2021 and 2025. This low annual mileage often protects the drivetrain from high wear, but it increases the likelihood of age-related issues such as the persistent corrosion and degradation of rubber components and metal brake lines. A buyer must prioritize a thorough physical inspection of the suspension and braking hardware. The August 2024 test at 98,506 miles flagged worn bushes on all four lower suspension arms and pitted front brake discs, while the 2023 record noted binding rear brakes and fluctuating discs. The recurring corrosion on all four brake pipes noted in 2021 and again in 2024 indicates a vulnerability to rust. You should verify if these pipes have been replaced or treated, as corroded hydraulic lines represent a significant safety risk if left untreated. Check the alignment and tyre condition, as the 2022 advisory for an uneven worn offside rear tyre suggests potential geometry issues or worn suspension components. Given the history of binding calipers and worn bushes, a test drive should focus on detecting play in the steering or vibrations under heavy braking. The lack of advisories in the 2025 test may indicate these issues were addressed, but the age of the vehicle means these components are likely nearing another cycle of failure.
