2009 BMW 520 2.0L Diesel · WR09 FUT

The most recent MOT inspection for this BMW 520, conducted in October 2025, resulted in a pass following the rectification of several minor lighting defects. While the vehicle has successfully passed its recent tests, the maintenance trend suggests a pattern of recurring minor electrical issues, specifically regarding the registration plate lamp and position lamp colours. More concerning is the persistent and long-term presence of advisories regarding the rear brake discs. These advisories have appeared consistently since at least 2023, indicating that while the vehicle remains roadworthy, there is a lack of proactive replacement of braking components, which may suggest a reactive rather than preventative maintenance approach by the current or previous owners. With a recorded mileage of 133,539 over approximately 17 years, the vehicle has covered an average of roughly 7,855 miles per year. This represents a relatively low-to-moderate annual usage rate, which is typical for a premium executive saloon that may have been used for commuting or occasional long-distance travel rather than heavy commercial use. Mechanically, this level of mileage is well within the expected parameters for a BMW engine of this era, but the lower annual distance can occasionally lead to issues related to vehicles being left stationary for extended periods. Such usage profiles can contribute to the observed surface corrosion on brake discs and the deterioration of rubber components, such as the drive shaft CV boot noted in the 2020 history. Prospective buyers should pay close attention to the braking system during a test drive. The repeated advisories for pitted and scored rear brake discs suggest significant surface oxidation or wear that has not been addressed. You should listen for any grinding noises during braking or feel for a pulsating sensation through the brake pedal, which would indicate warped or unevenly worn discs. Furthermore, the 2021 failure regarding parking brake efficiency suggests that the handbrake mechanism or the rear calipers may be prone to sticking or losing effectiveness. It is essential to verify if the rear brake discs and pads have actually been replaced since the 2025 advisory, as continued use of scored discs will lead to poor stopping performance and accelerated wear on new pads. Beyond the braking system, the history of suspension and drivetrain advisories warrants a thorough physical inspection. The 2023 advisory regarding a worn rear suspension arm bush indicates that rubber components are reaching the end of their service life; listen for dull thuds or clunks when driving over speed bumps or uneven road surfaces, as failing bushes can compromise handling and tyre wear. Given the vehicle's age and relatively low annual mileage, you should also inspect the tyres for sidewall cracking or perishing, which occurs when rubber hardens due to age regardless of tread depth. Finally, check the engine bay for any signs of fluid leaks and verify the service history to ensure that essential calendar-based maintenance, such as oil changes and coolant flushes, has been performed to prevent degradation from long periods of inactivity.
