BMW 5 Series MOT failure rates: what fails, what to fix

TL;DR

BMW 5 Series models often face MOT failures primarily due to brake and suspension issues, particularly in older vehicles. Common problems include electrical faults and structural concerns, with repair costs ranging from £150 to £600. Understanding these issues can help buyers and sellers make informed decisions.

Common Failure Categories

The BMW 5 Series frequently fails MOTs due to brake and suspension issues. Brake failures often relate to worn pads or discs. Suspension problems are typically linked to worn bushes or shock absorbers. Both categories are crucial for safety and can be costly to repair. Additionally, owners have reported electrical problems, particularly with the lighting system, which can also contribute to MOT failures.

Age-by-Age Failure Rates

Failure rates tend to increase as the vehicle ages. For example, 5-year-old models may have a failure rate of around 15%. This can rise to over 30% for vehicles older than 10 years. Regular maintenance can help mitigate these risks. Owners have noted that models from the earlier years of the 5 Series, particularly those manufactured before 2010, may exhibit more frequent issues than newer iterations.

Quick Fixes vs Structural Issues

Many common failures can be resolved with quick fixes. Replacing a blown bulb or adjusting brakes may only cost a small amount. However, structural issues such as rust on the chassis or frame can lead to extensive repairs that might cost hundreds or even thousands of pounds. Owners have indicated that while minor fixes are often straightforward, more significant structural problems can be a deal-breaker when considering a purchase.

Cost Ranges for Typical Failures

Repair costs for the BMW 5 Series vary by issue. Brake repairs generally range from £150 to £400. Suspension repairs can be between £200 and £600. Lighting issues, such as bulb replacements, are often under £100. It is wise to budget for these repairs when considering an older model. Furthermore, owners have shared that the costs can escalate quickly if multiple issues arise at once, especially in older vehicles.

What owners say

Owners on r/BMW frequently discuss the reliability of the BMW 5 Series, noting that while many have had positive experiences, issues can arise depending on the specific model and year. For instance, some users have highlighted that the 2018 models tend to be more reliable, particularly with the petrol engines, whereas earlier diesel variants have been flagged for their susceptibility to problems.

Common faults reported by owners on r/CarTalkUK include suspension wear and electrical glitches. Many have shared that while the diesel engines offer excellent torque and fuel efficiency, they require diligent maintenance to avoid costly repairs. Users have also pointed out that regular servicing is crucial, especially for models over five years old, to maintain reliability.

In discussions about value, several owners remarked on the depreciation of older models, making them attractive options for budget-conscious buyers. However, they caution that potential buyers should be aware of the maintenance history and common issues associated with specific years, particularly those from the F10 generation.

Additionally, buyers in UK communities have flagged that certain years, like 2011-2013, should be approached with caution due to known issues with the timing chain and electrical systems. Overall, while the BMW 5 Series is often regarded as a solid choice, prospective buyers should conduct thorough research and consider the specific model year before making a purchase.
