Summary Verdict
The 2010 Audi A4 offers a premium driving experience but is not without its potential mechanical and electrical quirks. The 2.0L TFSI engine is prone to oil consumption and issues with the PCV system and timing chain tensioners, which can be costly to repair. The 3.2L V6 also faces timing chain concerns. Automatic transmissions, particularly the CVT, can be a source of expensive repairs. Suspension components like control arm bushings and wheel bearings are common wear items. While electrical issues are less prevalent, infotainment glitches can occur. Despite these points, many A4s remain reliable with diligent maintenance and prompt attention to emerging problems.
