2013 BMW 520 2.0L Diesel · MT63 AAF

The 2013 BMW 520 has passed its most recent MOT test on 2025-11-27 with no recorded defects, following a consistent pattern of passing examinations over the preceding six years. While the vehicle’s MOT history is otherwise clean, the presence of minor defects and advisories in earlier tests—such as the condensation in the offside headlamp lens in 2023 and the dampness noted inside the nearside headlamp in 2022—suggests a minor but persistent issue with the headlamp assemblies. These advisories, though not failing the vehicle, indicate potential long-term exposure to moisture or condensation within the headlamp housings, which could lead to electrical or optical degradation over time. The absence of repeated failures or more severe advisories in the intervening years implies that the vehicle has been maintained adequately, but the buyer should monitor these components closely, particularly if the car is exposed to prolonged periods of damp conditions or frequent use in wet environments. The recorded mileage of 107,751 miles for a 13-year-old BMW 520 represents a reasonable annual usage rate of approximately 8,289 miles per year, which aligns with typical driving patterns for this age group. The mileage progression does not appear to be unusually high or low, suggesting a balanced usage profile rather than heavy or light service. However, the vehicle’s age and mileage do warrant attention to certain wear areas, particularly those prone to accelerated degradation from prolonged standing or infrequent use. For instance, standing for extended periods can lead to brake disc corrosion, binding calipers, or seized suspension components, while fluid degradation—such as in the brake fluid reservoir or coolant system—can occur over time due to calendar-based aging rather than mileage alone. Given the vehicle’s clean MOT history aside from the headlamp-related advisories, the buyer should conduct a thorough physical inspection to address potential age-related wear and tear. Start with the tyres, checking for sidewall cracking or perishing, which can weaken their structural integrity and reduce tread life. Inspect the 12V battery for signs of corrosion around terminals, poor electrical connections, or reduced cranking power, especially if the car has been stored for extended periods. The brakes should be examined for uneven wear, binding calipers, or corrosion on the discs, which may indicate standing corrosion or previous dry-brake episodes. Additionally, verify the service history for time-based fluid servicing, such as the brake fluid flush every two years and the coolant change every five years, as these are critical for maintaining performance and preventing corrosion or hydraulic failure. During a test drive, listen for any unusual noises such as clunking from the suspension, particularly when driving over bumps or at speed, which could indicate worn suspension bushes or coil spring failure. Check for excessive vibration in the steering wheel or pedals, which may signal misaligned wheels, warped brake discs, or drivetrain issues. Monitor the braking performance for any signs of sponginess, pulling, or uneven stopping distances, which could reveal issues with brake fluid contamination, worn pads, or warped discs. Finally, ensure the exhaust system is free from leaks or unusual noises, as a compromised catalytic converter or flex pipe could lead to emissions-related failures or increased fuel consumption. The headlamp advisories should be addressed by cleaning or replacing the affected lenses and housings to prevent further moisture ingress, and the buyer should consider a professional inspection of the electrical system to confirm the stability of these components.
