2016 BMW 520 2.0L Diesel · AE66 MZL

The most recent MOT test for the 2016 BMW 520 was conducted on 2026-08-19 and resulted in a passing grade, though it included two advisories that warrant careful consideration. The pattern of MOT results over the past four years shows a stable maintenance record with no failures, but the recurring tyre-related advisories—specifically nearside rear tyre wear approaching the legal limit and an offside rear tyre nail—suggest a persistent issue with tyre management or road conditions encountered. While the vehicle has not failed an MOT, the advisories indicate that tyre wear is not being monitored adequately, which could escalate into a failure if not addressed promptly. The absence of other defects or advisories in the intervening MOTs suggests that, aside from tyres, the vehicle’s structural integrity, emissions system, and core mechanical components are holding up well under current usage. The vehicle’s recorded mileage of 156,836 miles at the time of this assessment is notably high for its age, reflecting an annual usage rate of approximately 15,684 miles, which is significantly above the average for a ten-year-old car. This level of mileage accelerates wear on consumables such as brake pads, suspension components, and fluid systems, as well as on structural elements like coil springs, bushings, and exhaust components. The rapid mileage accumulation suggests either intensive driving conditions—such as frequent short trips, towing, or aggressive driving—or periods of prolonged use without adequate maintenance breaks. For a BMW 520, which is known for its robust yet precision-engineered drivetrain and suspension, this mileage places greater emphasis on proactive checks for wear in the drivetrain, exhaust system, and suspension geometry, where cumulative stress can lead to premature failure of seals, bearings, or bushings. Given the recurring tyre advisories and the high mileage, the prospective buyer should conduct a thorough inspection of the tyres, focusing on the nearside rear tyre for signs of uneven wear patterns, bulges, or cracks that could indicate underlying suspension or alignment issues. On a test drive, listen for unusual noises from the rear suspension, such as clunks or rattles, which may suggest worn suspension bushes or damaged coil springs. Inspect the rear tyres for lateral wear, which can be caused by misalignment, and check the tread depth consistently across the face of the tyre. Additionally, verify that the vehicle’s brake system is functioning correctly, as high mileage can lead to brake pad or rotor wear, potentially causing binding or shuddering when braking. If the tyres are not replaced soon, the nearside rear tyre’s edge wear could lead to a failure in the next MOT, highlighting the importance of addressing this immediately. Beyond tyres, the buyer should examine the vehicle’s fluid levels and condition, particularly the engine oil, brake fluid, and coolant, as these degrade over time and mileage. Given the BMW’s reputation for precision engineering, the drivetrain and transmission should be checked for leaks or unusual resistance during gear changes, while the exhaust system should be inspected for leaks or excessive backpressure, which could indicate catalytic converter or manifold issues. The suspension components, including the upper and lower control arms, coil springs, and shock absorbers, should be inspected for signs of corrosion, excessive play, or damage, as high mileage can accelerate wear in these areas. Finally, a visual and functional check of the exhaust emissions system is advisable, as BMWs are subject to stringent Euro emissions standards, and any failure here could result in a costly repair or further MOT issues. For the specific advisories noted, the buyer should prioritise tyre replacement to the legal minimum tread depth and consider a professional inspection of the suspension and alignment to prevent further wear progression.
