The BMW 520 has long been a staple in the executive sedan market, known for its blend of performance, luxury, and technology. Since its introduction in the mid-1990s, the 5 Series has garnered a reputation for being a well-rounded vehicle, appealing to both business professionals and families alike. However, a deeper look into the reliability and maintenance aspects reveals a mixed bag of performance across various model years.

When analyzing MOT inspection data, the BMW 520 exhibits fluctuating reliability over the years. Early models, particularly from 1995 and 1999, show a higher average defect rate of 346 and 375 defects per 100 tests, respectively, which is above the averages for their model years. Notably, the recurring issues during these years include problems with brake pipes, worn suspension components, and tyre condition, suggesting areas that could benefit from greater engineering focus.

In contrast, the later years from 2010 to 2022 demonstrate significant improvements in reliability. For instance, the 2010 model records just 192 defects per 100 tests, a 35% improvement compared to the average of its year. The trend continues, with the 2022 model achieving a remarkable 51 defects per 100, which is 27% better than the average. This downward trajectory in defect rates highlights BMW's ongoing commitment to enhancing the durability and safety of its vehicles.

Despite these advancements, the 520 has had its share of persistent issues, particularly related to tyre tread depth and various brake components. Such problems are common across most model years, emphasizing the need for regular maintenance checks, especially concerning the vehicle's braking system and tyre health.
