    astra coupe turbo whines in 2nd and 3rd gear

    Ok im after opinionings please.
    I have a medium pitched whining noise come from the gearbox i think just as the turbo comes in, in 2nd and 3rd gear only. 2nd gear the noise is loud but when in 3rd the noise is less noisey and lower frequency and in 4th you cant hear it.
    Now ive checked the turbo impaller for play and its fine and there is no oil loss or smoke etc.
    Its not the alternator and both front wheel bearings have been changed last year.
    No power loss but 1 thing i have noticed in the last week is sometimes my clutch pedal slightly vibrates when pulling away in 1st gear and the pedal has becomes very light after ive put my foot down.
    I know its a stab in the dark but its worth a try.
    someone may have had a similar problem.
