PCV System Malfunction

The Positive Crankcase Ventilation (PCV) system can fail over time, leading to increased oil consumption, rough idling, and potential seal leaks. Estimated repair cost: $300 - $800.

Carbon Buildup on Intake Valves

Direct-injection engines like the S5's 3.0L V6 are prone to carbon buildup on intake valves, which can restrict airflow and reduce performance. This is exacerbated by infrequent high-RPM driving. Estimated repair cost: $600 - $1,200.
