STELAN Aftermarket AOS

Stelan,
Sounds promising.
Just a thought - the PCV intended for a 1.8L VW may have inadequate vacuum flow for the 3.2L ? Use one intended for a larger engine? See Post 47 for the Audi Part #.
But a generic would be cheaper.

good call however the 1.8t is well capable of flowing more than enough, that is not an issue. diaphragm in both oem 2.5/2.7 and 3.2 are similar, the amount of flow is dictated by the rapid opening and closing vibrations of the diaphragm based on TB pressure/vacuum signal.
