2009 BMW 520 2.0L Diesel · MT59 JXO

The vehicle is currently roadworthy, but the maintenance trend indicates a shift toward reactive rather than preventative maintenance. While it passed its most recent test in November 2025 at 194,546 miles, this followed an immediate failure due to critical safety defects. The failure noted on the nearside brake pipe caused by excessive corrosion near the fuel tank and rear sill suggests that structural degradation of the braking system was ignored until it reached a point of failure, despite the clean records seen in the preceding three years. The mileage accumulation is consistent with a 17-year-old vehicle, averaging approximately 11,400 miles per annum. Between October 2022 and November 2025, the car covered 29,544 miles, representing a steady usage pattern of roughly 9,800 miles per year. The jump from 165,002 miles in 2022 to the current reading shows no significant gaps, suggesting consistent operation, though the high total mileage places considerable mechanical stress on the drivetrain and suspension components typical of a BMW of this era. A buyer must conduct a thorough physical inspection of the rear braking system, specifically focusing on the condition of the feed pipes and the surrounding sill area. The presence of grease on the nearside rear brake pipes during the 2025 test is a red flag, as it often indicates an attempt to mask a leak or weeping joint. Furthermore, the report of both rear tyres being worn close to the legal limit with uneven edge wear suggests a potential alignment issue or worn suspension bushes that should be verified to prevent premature scrubbing on new rubber.
