Detailed Description

The Vaico V10-3103 PCV valve helps regulate crankcase vapors by maintaining controlled pressure and preventing reverse flow through the ventilation circuit. This matters for emissions performance, idle quality, and overall crankcase ventilation function. It is listed for 2001-2004 Volkswagen Golf, 2003 Volkswagen Jetta, and 2003-2006 Audi TT and Audi TT Quattro applications, making it a focused choice for owners searching by OE number 035 103 245 G or by vehicle fitment.
