2015 BMW 520 2.0L Diesel · W12 BAT

The vehicle maintains a roadworthy status, though the maintenance trend shows the first signs of age-related wear. While the car achieved four consecutive passes without defects between 2021 and 2024, the inspection in September 2025 at 120,872 miles identified rear brake discs as worn, pitted, or scored. This indicates that the braking system is reaching the end of its service life after years of clean records. The mileage profile is consistent with typical UK usage for an executive saloon, averaging approximately 11,000 miles per annum. There is a notable increase in activity between September 2023 (76,017 miles) and August 2024 (99,541 miles), where the vehicle covered over 23,000 miles in just eleven months. Since then, usage has remained high with another 21,000 miles recorded before the final test. This high-intensity period explains the accelerated wear observed on the braking and suspension components. A buyer should prioritize a physical inspection of the braking assembly to determine if the pitting on the discs is indicative of surface corrosion or persistent binding calipers. Given the high mileage and the recent advisory regarding the discs, a thorough check of the suspension bushes and control arm bolts is necessary as these are common points of failure on this chassis at this age. There are no structural issues or mechanical failures recorded in the history, but the shift from clean tests to mechanical warnings suggests that preventative maintenance is now becoming critical.
