Audi Genuine PCV breather unit, EA839 2.9T / 3.0T (06M103515H)

The PCV (Positive Crankcase Ventilation) valve, also known as a “breather” or “oil separator,” is a crucial component in your engine’s crankcase ventilation system. It ensures the proper expulsion of crankcase air while preventing oil leaks during operation. A faulty PCV valve can lead to symptoms such as misfires, rough idle, or a whistling noise, all of which can compromise engine performance. Replacing a malfunctioning PCV valve is essential to maintain optimal engine functionality and avoid costly repairs.
