New Beetle (type 1C, 9C & 1Y) 1997 - 2011
2006 Beetle 1.6L BFS
The upper intake was whistling so I removed it and the issue is the 'valve' underneath it. (I believe on newer ones the valve is on top)
Anyway there is a membrane on what is similar to newer pcv membranes. THere is also a pivot arm attached to it and that is what is...
