Overview

2015 Audi A4

The 2015 Audi A4 presents a compelling package for used car shoppers seeking German engineering and a refined interior. It boasts a strong safety record with perfect NHTSA scores across the board. Fuel economy is respectable for its class, making it a practical choice for daily commuting. However, a high volume of Technical Service Bulletins (TSBs) warrants careful consideration, as these often signal potential, albeit non-safety-critical, issues that could impact long-term ownership costs.

Critical Failure Risk

The Positive Crankcase Ventilation (PCV) valve can fail, leading to oil consumption and potential vacuum leaks.

Early detection can help you avoid a $700-$1,100 repair.
