Summary Verdict

The 2009 Audi A5 is a desirable vehicle with a generally good reliability record, particularly for its more powerful engine options. However, potential buyers should be aware of common issues such as oil consumption and timing chain wear on the turbocharged 2.0L TFSI engine, and potential mechatronic unit or clutch pack issues with the automatic transmissions. The convertible model may also face hydraulic top system concerns. While electrical and interior components are mostly robust, infotainment glitches and HVAC blend door issues can occur. Regular maintenance and prompt attention to any unusual noises or warning lights are crucial for maintaining the A5’s long-term reliability and value.
