    Does anyone else have the problem of a hissing noise coming from under the car, on the passenger side?
    It only happens at about 4000rpm in 6th, otherwise i have never heard it.
    I know its not the turbo, cos its not quite that sound, and the location its coming from doesn't make sense.
    If i had to guess, it sounds like a split hose or something down there but no idea what it could be..
