What Tends to Fail First on the 2017 Audi A6

The systems that tend to fail first on the 2017 Audi A6, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

1
Electrical/Infotainment Systemmoderate~40,000-80,000 mi

The Multi Media Interface (MMI) can experience glitches, freezing, or intermittent functionality. Sensor failures (e.g., parking sensors, wheel speed sensors) and door lock actuator failures are also common. These issues are often softwa…

2
Air Suspension System (if equipped)major~60,000-100,000 mi

Vehicles equipped with the optional adaptive air suspension are prone to air spring leaks (often identified by a sagging corner overnight) or compressor failure. While providing a superior ride, these components are expensive to replace,…

3
Cooling System Componentsmoderate~70,000-110,000 mi

Particularly on the 3.0T supercharged engine, the water pump and thermostat housing are known to develop leaks. This is often due to plastic components becoming brittle over time or seal degradation. Overheating can lead to severe engine…
