MOT Pass Rates
MOT pass rates for the BMW 5 Series reveal a mixed picture. The average pass rate is around 63%, which is below the national average for cars in the UK. Some years, particularly from 2005 to 2010, have shown lower pass rates due to various mechanical issues.

The most frequent issues reported include electrical faults, oil leaks, and problems with the cooling system. Electrical issues often arise in models from 2005 to 2010, where wiring harness failures are common. Oil leaks are prevalent in models with the N47 engine, particularly from 2007 to 2011.
Model Years to Favour
Models produced between 2010 and 2016 generally show better reliability. These years have fewer reported issues and higher owner satisfaction ratings. The F10 generation, specifically, is often praised for its driving experience and overall build quality.
Model Years to Avoid
Be cautious with models from 2005 to 2010. These years have higher rates of MOT failures and common faults. The E60 generation is particularly noted for its electrical problems and cooling system failures, leading to expensive repairs.
