Genuine VAG EA113 PCV Breather Valve

The Racingline Genuine VAG EA113 PCV Breather Valve (Part Number 06F 129 101R) is a direct replacement for the Positive Crankcase Ventilation valve on VAG Group's 2.0 TFSI EA113 engines, specifically those with a transverse mounting configuration. The PCV valve is a known failure point on these engines; its internal diaphragm can degrade over time, resulting in symptoms such as rough idling, noticeable vacuum leaks, general poor running, and potentially triggering check engine lights. This product is the genuine VAG updated part, ensuring correct fitment and the latest internal design revisions to address common failures. The PCV valve's function is to manage crankcase pressure by venting blow-by gases back into the intake system for re-burning. A split diaphragm compromises this pressure regulation, leading to the aforementioned drivability issues. Symptoms of a failing PCV valve can include a rough or lumpy idle, loss of power or hesitation under load, whistling or hissing sounds from the engine bay, lean running fault codes, and excessive oil consumption or oil ingestion into the intake. By fitting this latest revision part, you can restore proper crankcase ventilation, resolve these running issues, and return the engine to smooth, factory-standard operation. This valve is specifically designed for transversely mounted 2.0 TFSI EA113 engines found in performance models from VW, Audi, SEAT, and Skoda, including the Golf GTI Mk5, Audi S3 8P, and Leon Cupra. It is explicitly not suitable for longitudinally mounted engines. Important installation notes: A new gasket is not included with this valve and must be purchased separately. Reusing the old gasket is not recommended, as it may lead to vacuum leaks and negate the benefits of replacing the PCV valve.
