Try adjusting the valve wheel on top of the BOV - it only has 3 settings but should be accessible from the engine bay.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Just installed the above into my 02 996tt. Wanted to use their 50/50 setting. Got it professionally installed, and requested 50/50 setting, but have absolutely NO blow off valve sound. Would have been nice if the 250.00 part atleast came with directions. Anyone Ever installed one of these? (yes.., ONE. Only 1 is apparently needed to replace the 2 factory valves) thanks all.

POST 2Original post

Well it could have been set at full recirc rather than 50/50. It is obviously not at 100% VTA or you are deaf :?: . Try adjusting the valve wheel on top of the BOV - it only has 3 settings but should be accessible from the engine bay. You may get a CEL with either the 50/50 or 100% VTA setting. You do know that it's a Porsche and not a Honda.... :floor:

This is a source reference. Confirm exact model applicability in the original material.
