golf 5 gti boost leak (diverter valve)  

Mine goes WEEEEEEEEE

i have the same on my 1.9 tdi ARL . when i let off the gas in 3rd and specially 4th it sounds like a blow off valve . can it be the n75?

Is this why turbo just wines then hooks

Mine sounds like all the air comes out of it

mine does this! its weird it has no leak when you first start driving then it randomly starts doing this. let it sit for a awhile then its good again. can that be that valve?

I have the same problem mine does it most of the time with half cold engine you think its also the diverterr valve?

Block it
