I wonder how quickly this would put your S3 into 'limp' mode!

    well to be honest im not sure, i think the S4 would run two seperate N75s.

    I ordered a new N75 from audi yesterday cost me £60 :faint: hopefully its a J valve

    The N75 valve is the crappest thing ever, and mine can be so varible.

    It controls the turbo actuator.

    Wont always come up with a fault code if its faulty mate, will just give you variable boost pressures and send you into soft limp mode.
