2016 BMW 520 2.0L Diesel · N233 JDC

The 2016 BMW 520 presents a stable and reassuring maintenance trend, with the most recent MOT conducted on 17 October 2025 at 98,109 miles returning a clean pass with zero defects. Every recorded annual test from 2021 through 2025 has passed first time with no advisories or failures, indicating consistent mechanical upkeep across multiple years. This is a well-maintained vehicle by MOT standards, with no recurring faults or emerging deterioration patterns visible in the record. The mileage progression tells a coherent story. Between October 2021 at 54,315 miles and October 2025 at 98,109 miles, the car covered 43,794 miles over four years, averaging roughly 10,950 miles annually. The annual increments are steady: 8,001 miles between 2021 and 2022, 8,136 between 2022 and 2023, 12,045 between 2023 and 2024, and 15,612 between 2024 and 2025. That final jump is notable and suggests heavier recent use, possibly longer commutes or motorway driving, which is generally kinder to a diesel engine than short trips but places greater demand on braking and suspension components at higher speeds. Despite the clean MOT record, a buyer should still carry out a thorough physical inspection. The absence of flagged defects does not guarantee the absence of wear. At nearly 99,000 miles, consumable items such as brake discs and pads, tyres, suspension bushes, and coil springs are likely approaching replacement intervals regardless of whether they have triggered a test advisory. The rear subframe mounting points and inner wing arches on this generation BMW deserve close attention for corrosion, as structural rust can develop without appearing on an MOT until it becomes severe. The N20 four-cylinder engine fitted to the 520d is known for timing chain stretch at higher mileages, so any rattling on cold start warrants immediate investigation. The clean five-year MOT history suggests a conscientious previous owner who kept the car in good order. That said, MOT records only capture a snapshot on test day. A pre-purchase inspection by a qualified mechanic, including a compression check and underbody examination, remains the most reliable way to confirm the car's true condition before committing to a purchase.
