Audi A4 Quattro issue description unclear in comments on Audi A4 Quattro

Some Audi A4 Quattro owners report experiencing excessive oil consumption, which can lead to engine issues and necessitate frequent oil top-ups or repairs. Additionally, airbag problems have been a recurring concern across various model years, affecting both older and newer versions, including the 2020 model. Water leakage is another common issue, particularly from the driver's and passenger's sides, often linked to a clogged plenum tray drain that can impact various vehicle components. Furthermore, timing chain problems, especially with the EA888 2.0-liter engine, have raised alarms among owners due to tensioner issues that could result in catastrophic engine failures, prompting Audi to offer settlements to those affected. These challenges underscore the importance of regular maintenance and prompt attention to warning signs to maintain the vehicle's performance and reliability.
