Random Flutter

[barnoon]

Ive noticed over the past few months that about once every say 2 weeks instead of my BOV going off I get massive amounts of flutter, I have an aftermarket Apexi BOV and usually it goes off all the time and I get next to no flutter but on some occasions for about an hour or so it wont go off and I just get massive flutter, the car still runs the exact same performance wise when this happens but I just wanted to know whats going on?

I also have a pod filter and front mount if that contributes to this at all, turbo is stock with 14psi.

Cheers guys.

Your bov is sticking shut or something is jamming it from opening, so instead of it letting the air out its causing it to go back through the turbo and out the intake causing a flutter noise.

This is the noise you would hear if you had no bov at all.
