2015 BMW 520 2.0L Diesel · M23 XAM

The 2015 BMW 520 presents a stable and reassuring maintenance trend, culminating in a clean pass on the most recent MOT dated 1 May 2025 at 79,522 miles with zero defects recorded. The preceding tests in April 2024 and April 2023 each show a failed attempt followed by a pass on the same or very similar mileage, indicating that any initial failures were promptly rectified before the retest. Across the entire recorded history, no advisories or defects have been logged, which is uncommon for a vehicle of this age and suggests diligent upkeep by the previous owner. The mileage accumulation is consistent and typical for an eleven-year-old saloon. Between the April 2023 pass at 71,338 miles and the April 2024 pass at 76,322 miles, the car covered roughly 5,000 miles in twelve months. The subsequent year saw only 3,200 miles added before the May 2025 test, pointing to a slight reduction in annual use more recently. There are no suspicious gaps or sudden jumps in the odometer readings, and the overall average of approximately 7,200 miles per year aligns with normal private ownership patterns rather than prolonged standing or excessive high-mileage use. Despite the clean MOT record, a buyer should still carry out a thorough physical inspection. The absence of flagged defects is encouraging, but it does not guarantee the absence of latent wear. Pay close attention to the condition of the rear brake discs and calipers, as binding or uneven wear can develop between tests without triggering an MOT failure until it becomes severe. Inspect the front and rear suspension bushes, drop links, and coil springs for deterioration, particularly given the car's age. Check the inner and outer tyre sidewalls for perishing and verify even tread wear across all four corners, as the 520's rear-wheel-drive layout can accelerate wear on driven components. Examine the underside for corrosion on subframes, sills, and brake lines, and confirm that the exhaust system remains free from leaks or excessive corrosion that could affect emissions compliance at the next test.
