2014 BMW 520 2.0L Diesel · R5 HNH

The BMW 520d’s most recent MOT history shows a vehicle that passed its last test in February 2026 with no defects, but only after a critical failure just five days prior due to exposed tyre cords on both rear inner tyres—a clear sign of neglected consumable maintenance. The pattern here is unstable, with the February 2026 failure marking the first recorded defect in over two years, yet the severity of the tyre issue suggests basic upkeep was overlooked. The windscreen washer failure, while minor, indicates either a loose connection or a blocked system, neither of which poses an immediate risk but should be checked for recurring faults. Prior to this, the 2025 test revealed thin rear brake pads and a child seat obstructing inspection, implying either deferred servicing or a previous owner who prioritised convenience over safety-critical components. Mileage accumulation has been steady but not excessive, averaging around 9,750 miles per year—a typical range for a 12-year-old vehicle. The most recent 1,084-mile jump between the February 2026 tests occurred over five days, which is unusual and may reflect either a rushed purchase or a deliberate attempt to pass the MOT without addressing the tyres. Earlier mileage checks show a consistent pattern: 12,766 miles between the 2024 and 2025 tests, and 11,296 miles between 2023 and 2024, suggesting regular but not aggressive use. There are no red flags in the mileage data itself, but the abrupt tyre failure in February 2026 contradicts the otherwise clean record, raising questions about whether the vehicle has been properly maintained between tests. For a buyer, the rear suspension should be scrutinised closely, particularly the shock absorbers, which showed light oil misting in February 2024—a sign of potential internal wear that could worsen if not addressed. The rear brake pads were flagged as thin in 2025, so a full inspection of disc thickness and caliper condition is essential, as binding or uneven wear could indicate deeper mechanical issues. Tyres remain a critical concern; while the exposed cords were rectified before the latest pass, check for uneven tread wear or internal damage, as this could point to alignment problems or underinflation. Structural integrity appears sound, but a thorough examination of the rear wheel arches and lower chassis for corrosion—especially in a BMW, which can suffer from rust in high-moisture environments—would be prudent given the vehicle’s age.
