I've had my 2007 Saab 9-3 Tid since August and it's suffered with a weird mechanical 'whiring' sound in all that time. It almost sounds like a worn baring, I contemplated it being the clutch but having done 4k miles there appears to be no other clutch related issues. The mystery noise only happens when in gear (moving, not stationary), however dipping the clutch, rolling in neutral or when applying the brakes the noise vanishes (hence my original guess at clutch or flywheel). I'd rather not get a garage to diagnose without a rough idea of the area of interest to keep cost down. There is no loss of power No overheating Fuel efficiency isn't affected No obvious adverse effects No clutch slip It's been driving me bloody crazy as you can hear (and feel it) all the time. Did wonder about the cambelt but no idea how a worn one manifests symptoms Help!
