Audi C5 Allroad 2.7T PCV Assembly
The Positive Crankcase Ventilation system on your Audi C5 Allroad is integral to the engine's ability to manage blow-by gasses and maintain emissions control.
The two-stage pressure relief valve channels air to the intake manifold and turbocharger while separating oil from the system.
Symptoms of a problematic PCV system are rough idling, misfires, and general poor performance.
