i am looking to but a BOV really soon for my car (within the next 2 weeks) an i want to buy a switchable BOV so that way i can adjust if it fully BOV or partial or full recirculation incase the woosh noise start to get to me (which i cant see happening anytime soon) but just to be safe. I know on ecs tuning there is one but i heard for some reason that i doesnt fit on the B7 so im not entirely sure about that one, but i was wondering if anybody had any experience with them and could recommend one to me. thanks guys!

 

forge adjustable dv valve

get it with the adjustable spacer, you can switch out the top piece of the dv with a spacer and different springs so it can be a bov, 50/50 split, or a full dv

its like 250 for the forge dv and then 50 more for the spacer

thats your best bet

 

alright cool, thanks a bunch man!

 

I don't mean to bump an ancient thread but..... is this the DV you are talking about? Audi B7 A4 FWD 2.0T > Engine > Intake > Diverter Valve > ES#1832057 2.0T FSI Replacement Bypass Diverter Valve - FMDVFSITV

Or this one... Audi B7 A4 Quattro 2.0T > Search > Forge > ES#1832059 Switchable Blow Off Valve - Polished - FMDVFSITAC

And is this the spacer?... Audi B7 A4 Quattro 2.0T > Search > Forge > ES#1832412 Atmospheric Blow Off Valve - Polished - FMDV14T

I have been reading up about this, but I cannot figure out which one people are referring to...

 

D stock Valve only!!! Forge spacer if you want woooooosh sound. Sticky up top covers this. Blow off = no, no
