Summary

The 2013 Audi A4 Quattro, while a desirable vehicle, has several potential issues that prospective buyers should be aware of. Engine problems, particularly excessive oil consumption and timing chain tensioner failure, can be costly to repair. Transmission issues with the 8-speed automatic can also be significant. Other problems, such as suspension bushing wear and electrical issues, are less severe but can still add to the overall cost of ownership. Prioritizing a pre-purchase inspection by a qualified mechanic familiar with Audis is highly recommended.
