    The"under membrane"part should be connected to turbo inlet hose.
    Yes its mounted so the small bore pipe faces the drivers wing.

    At what pressure should the BOV creep open?

    Whilst boost leak testing my S2 (from the turbo to intercooler hose) I noticed the dump valve started to open and flow air at about 0.8 bar. Is this correct? same result was found with OE, Forge and forge copy BOV.

    This may not happen when driving as the small bore pipe will be seeing boost and helping keep the BOV closed?

    Thanks, Dan.
