2005 BMW 525 2.5L Petrol · G6 SOV

The vehicle presents a concerning maintenance trend characterized by recurring mechanical issues that have persisted through the most recent recorded test in December 2022. While the car passed its last MOT, the tester flagged several advisories including pitted or scored nearside front brake discs, play in the steering rack inner joints, and an ongoing oil leak. These issues are not new; the steering rack play was first noted in November 2021 at 124,979 miles and the oil leak has appeared intermittently since at least January 2013. The lack of recent testing data since December 2022 suggests the vehicle has been off the road or its MOT status has lapsed for over three years, which is a significant red flag for a buyer. The mileage history shows a consistent, albeit slow, accumulation of approximately 6,300 miles per year, which is typical for a vehicle of this age. The record shows steady progress from 50,835 miles in January 2013 to 132,430 miles in December 2022. However, the significant gap in MOT documentation from late 2022 to the current date of July 2026 means the current roadworthiness cannot be verified. The long intervals between tests and the presence of multiple failures in earlier years, such as the 2015 failure for lighting and tyre tread depth, suggest a history of reactive rather than preventative maintenance. A prospective buyer must prioritize a thorough inspection of the steering and suspension systems. The steering rack inner joints have been flagged for play across multiple tests, specifically in 2021 and 2022, indicating a worsening condition that likely requires replacement. The recurring advisories for suspension arm bushes and anti-roll bar linkages between 2017 and 2019 further suggest the front end may require significant refurbishment. Given the long-standing oil leak noted since 2013, a detailed check of the engine bay and underbody is essential to determine the severity of the leak and whether it has caused secondary damage to rubber components or electrical wiring. Finally, the braking system requires immediate attention. The December 2022 advisory regarding pitted and scored brake discs indicates that the friction surfaces are degrading. Because the vehicle has not had a recorded test in several years, the buyer should also inspect all consumables, including tyres and wiper blades, as well as checking for any signs of corrosion on the chassis or exhaust system that may have developed during periods of inactivity. The history of lighting failures and airbag warning lamps in 2014 and 2015 suggests that the electrical system should also be tested for reliability.
