PCV Valve 06F129101R For Audi A3 A4 A6 TT VW Golf GTI Jetta Passat Eos — OEM Breather Valve
Product Overview
The Positive Crankcase Ventilation (PCV) Valve with OEM reference number 06F129101R is a verified direct-fit replacement for a wide range of Audi, Volkswagen, and SEAT vehicles equipped with the 2.0T FSI / TFSI engine (EA113 engine family). This valve regulates and vents blow-by gases from the crankcase back into the intake manifold for combustion.
Critical Fitment Note: This PCV valve is specifically designed for the FSI engine only. Verify on your engine cover that it is stamped "FSI" (not TFSI). This is the latest revision (R), superseding previous versions 06F129101L, 06F129101N, and 06F129101K.

⚠️ Important Build Date Split (B7 A4 2.0T):
- Early version (build date BEFORE 16.12.2005): PCV valve HAS a check valve
- Late version (build date AFTER 16.12.2005): PCV valve has NO check valve
Installing the wrong PCV valve can cause idle issues. Always verify your vehicle's original part number and build date before ordering.
