Product Details

This aftermarket replacement engine valve cover is designed for the VAG 3.6L V6 FSI engine platform, fitting a wide range of Volkswagen and Audi applications. Replacing a failed or cracked valve cover restores proper crankcase ventilation and prevents unmetered air from entering the intake, which can cause rough idle, misfires, and hard starting conditions.

The valve cover integrates a PCV (Positive Crankcase Ventilation) diaphragm membrane, which is a common wear component on these engines. Over time, the diaphragm can dry out, crack, or tear, allowing uncontrolled air to bypass the mass air flow sensor and disrupting the air/fuel mixture. Replacing the valve cover assembly restores the factory crankcase ventilation system to proper function.

Key Features:

  • Direct aftermarket replacement for OEM part number 03H103429H
  • Designed for the VAG 3.6L V6 FSI / VR6 engine
  • Integrated PCV crankcase ventilation diaphragm membrane
  • Restores proper idle quality, reduces misfires, and prevents unmetered air intrusion
  • Includes valve cover gasket and hardware as applicable

Cross-Reference Part Numbers: 03H103429H, 03H103429C, 03H103429D, 03H103429B, 03H103429L, 03H103429K, 03H103429S, 022103515A
