Rubber Valve Cover Diaphragm Membrane Replacement 3.2L 3.6L V6 for Audi Q7 A3 TT

Keep your 3.2L and 3.6L V6 engines breathing cleanly with the Tree of Life Rubber Valve Cover Diaphragm Membrane. Designed as a durable rubber replacement, this diaphragm plays a crucial role in the valve cover and PCV system, sealing vacuum paths and ensuring consistent engine ventilation. When the diaphragm wears or cracks, you can see increased oil migration, rough idle, and reduced efficiency. This part provides a reliable, cost-effective fix that restores proper engine breathing for a smoother, more efficient ride.

Compatible with a broad range of models including Audi Q7 3.6L (2007–2013), Audi A3 3.2L (2004–2009), Audi TT 3.2L (2004–2009), VW R32 3.2L (2008), VW Passat 3.6L (2006–2016), VW CC 3.6L (2008–2013), VW Touareg 3.6L (2007–2016), VW EOS 3.2L/3.6L (2007–2016), and Porsche Cayenne 3.6L (2007–2012). It does not fit VW Jetta, GTI, or R32 3.2L (2002–2004). Crafted from quality rubber and backed by OEM-referenced part numbers, this diaphragm is a functional, close-to-original replacement that simplifies maintenance and helps protect engine longevity.

From a maintenance perspective, this diaphragm is a smart pick for preventive care. Replacing a worn diaphragm can prevent vacuum leaks and avoid more involved valve cover repairs later, saving time and money while keeping your engine's breathing clean and consistent. The part is designed for straightforward installation by technicians familiar with Audi, VW, and Porsche V6 engines, helping you get back on the road quickly.
