Summary Verdict
The 2010 Audi A5 presents a generally reliable package, particularly with the manual transmission and standard chassis. However, potential owners should be aware of specific engine concerns like oil consumption in the 2.0L TFSI and timing chain wear in the 3.2L and V8 variants. Automatic transmissions, especially the S tronic, can be prone to mechatronic unit and clutch pack issues. Electrical gremlins, particularly with the MMI system, are also noted. For the convertible models, the top’s hydraulic system requires attention. Regular maintenance and prompt attention to early symptoms are key to mitigating these potential costs and ensuring a positive ownership experience.
