2016 BMW 520 2.0L Diesel · ML66 AAN

The most recent MOT test on 2026-08-24 returned a clean pass, indicating no defects were recorded at that time. However, the vehicle’s MOT history reveals a pattern of recurring advisories over the past three years, particularly concerning brake system components and tyre wear. While the latest test shows no active failures, the consistent presence of thin brake pads and worn brake discs—both front and rear—suggests a maintenance trend that has not been fully resolved. The advisories from 2023 and earlier indicate progressive wear, which could imply either under-maintenance or inherent high-friction braking conditions, such as aggressive driving or prolonged periods of light use leading to brake pad and disc degradation. The inclusion of "under shields fitted!" in 2023 may also hint at a past repair or modification, potentially affecting future inspections if not properly documented. The vehicle’s recorded mileage of 89,805 miles at the time of assessment represents approximately 8,980 miles per year, which is within the expected range for a 10-year-old BMW 520 under typical UK usage patterns. This rate does not suggest excessive wear from high annual mileage, but it does not rule out the possibility of prolonged periods of inactivity, which can exacerbate issues like brake pad and disc wear due to standing corrosion or brake fluid degradation. The absence of significant mileage spikes or rapid accumulation over shorter periods would be reassuring, as such behaviour might indicate higher-than-normal stress on drivetrain or suspension components. However, the advisories from previous MOTs suggest that the brakes have been subjected to wear beyond normal expectations, warranting closer attention to their condition. To proceed with a thorough inspection, the prospective buyer should focus on the brake system first, as the advisories indicate ongoing wear. Visually inspect the brake pads and discs for further thinning or damage, checking for any signs of glazing or scoring that could compromise braking performance. On a test drive, listen for unusual noises such as squeaking or grinding, which may indicate pad-to-disc contact or warping. Additionally, check for any brake pedal pulsation or vibration, which could signal warped discs or binding calipers. Inspect the rear brakes for uneven wear patterns, as the 2023 advisory noted offside tyre wear, which may correlate with rear brake drag or misalignment. Fluid leaks around the brake calipers or master cylinder should also be scrutinised, as brake fluid degradation over time can lead to reduced effectiveness and corrosion in the system. Beyond the brakes, the vehicle’s tyre condition should be assessed carefully, particularly the inner edges of the front tyres, which were noted as worn close to the legal limit in 2023. Check for sidewall cracking or perishing, which is more common in older vehicles due to exposure to UV light and temperature fluctuations. Given the vehicle’s age and the advisories, it is prudent to verify the brake fluid level and condition, as standing fluid can absorb moisture and lower braking efficiency. A visual inspection of the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of wear or damage is also advisable, especially given the potential for standing corrosion in the rear suspension area. Lastly, the battery should be checked for signs of corrosion or weakness, as prolonged inactivity can lead to reduced capacity or failure. If the vehicle has been driven regularly, ensure the service book or maintenance records are up to date, particularly for fluid changes and timing belt replacement, which are critical for long-term reliability.
