MOT Pass Rates

The Audi A6 generally performs well in MOT tests, particularly models from 2015 onwards. These newer versions boast an average pass rate of around 80%. In contrast, older models, especially those from 2005 to 2010, show a significant drop in pass rates, often below 70%. This suggests that while the A6 is a solid choice, buyers should favour more recent models for better reliability.

Common Failure Modes

Several recurring issues have been noted across various model years. Electrical problems are frequently reported, particularly in models from 2011 to 2014. Oil leaks, notably from the turbocharger and valve cover gaskets, are also common. Suspension wear is another issue, especially in vehicles that have been driven extensively on rough roads. Repair costs for these issues can range from £200 for minor fixes to £1,500 for more significant repairs.

Year-by-Year Notes

Models from 2015 onwards generally show improved reliability, thanks to better build quality and engineering. The 2011-2014 models have a mixed reputation, with many owners reporting issues that can lead to costly repairs. The 2005-2010 models, while still popular, often face higher maintenance costs and more frequent failures. If you are looking for an A6, aim for the 2015 model year or newer to avoid the pitfalls of earlier versions.

Owner Reviews and Feedback

Owner feedback is generally positive, especially for models produced after 2015. Many owners praise the comfort, performance, and technology features. However, some owners of older models have shared concerns about reliability and the cost of repairs. This mixed feedback highlights the importance of thorough research and inspection before purchasing.
