The Positive Crankcase Ventilation system on your Audi A3 8P is integral to the FSI 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.
ECS has assembled a complete PCV refresh kit for your Audi, including a PCV breather tube, Pressure Relief Valve, and new gaskets and hardware.
