2015 BMW 520 2.0L Diesel · SF65 AAW

The 2015 BMW 520 has demonstrated a consistent roadworthiness pattern over its MOT history, with all five tests—spanning from June 2022 to March 2026—resulting in clean passes and no recorded defects. The most recent inspection, conducted on March 13, 2026, at 85,607 miles, confirms the vehicle remains within DVSA compliance for its current condition. While no advisories or major failures appear in the record, the absence of any recorded issues across these tests suggests the vehicle has not experienced recurring mechanical or structural problems that would warrant concern. However, the lack of defects does not preclude the need for a thorough independent inspection, particularly for components not routinely assessed during an MOT. The mileage progression reveals a steady accumulation of approximately 7,782 miles annually, which aligns with typical usage for a vehicle of this age. There are no abrupt jumps or prolonged periods of inactivity between tests, with the most notable gap between February 2023 (50,115 miles) and June 2022 (50,041 miles) amounting to just 174 miles over six months—likely due to the staggered MOT cycle rather than neglect. The consistency in mileage suggests the vehicle has been driven regularly without extended periods of disuse, which could otherwise accelerate wear on fluids, seals, or suspension components. Given the clean MOT history, a buyer should prioritise an inspection of high-wear items not fully covered by the test, such as the suspension’s rubber bushes and coil springs, which may exhibit fatigue or cracking after nearly 11 years. The braking system, while not flagged in the MOT, should be scrutinised for uneven pad wear, binding calipers, or corrosion on the rear discs—common issues in BMWs of this era. Additionally, the exhaust system warrants close examination for leaks or excessive rust, particularly around the catalytic converter and downstream muffler, as these are often overlooked until they fail. Finally, the underbody should be checked for structural corrosion, especially around the wheel arches and sills, where salt ingress can compromise the chassis over time.
