Strange PF PF PF PF sound
2 weeks ago my chargepipe came loose. drove aroud for 2 weeks and 2 weeks later i reconnected the chargepipes.
Bur now the BOV wont open, and i hear a PF PF PF PF PF PF PF sound when im shifting gears.
i have a greddy-look BOV. and im running @ 4,5 psi boost.
the sound is like a sqq bov, but al lot more quiet.
i disconnected the BOV and noticed it was working normal, i never changed anything to my setup, but 1 took out 1 spring of the bov, and adjusted it to soft.
now the PSSSSFFHHH sound is back, but not as loud as it was before. and i still hear the PF PF PF PF sound.
the sound is comming from the disconnected charpipe or tubro or somewhere over there.
i cant test it when im in neurtral, because there wont be boost.
I need help

I think it's because your living two weeks into the future. It's not working right cause the boost hasn't even been created yet.

I still hear the sound. and the bov is working, ive read some stuff about surge, but befor the chargepipe popped of, i never had this sound.
the bov has 1 vacuum nipple. i dont think its a bov problem.. the pf pf pf is comming from the other side in the engine bay.

ya its coming from the other side of the engine bay...aka where the turbo is..and as everyone else said its compressor surge meaning your bov is not opening properly either because theres a vacuum leak..or its just fucked.
