Hi, noticed the last few days I can hear a high pitched whining noise, from the engine bay I reckon (300tdi). I can only hear it when the engine is under load or decelerating, seems to be definitely engine speed related rather than road speed, if I slip it into neutral and coast there's no whine and it's not related to the clutch being in or out. We've had the stereo on a very low volume for a few days and at first I thought it was interference from the ignition but today I turned it off and the noise was still there, it's not really loud but it is noticeable and the wifey can hear it and she knows nowt about engines and how they should sound! Seems more pronounced the higher the revs, when we got home I tried with the car stationary and it was hard to hear it til revs were up to about 2.5k - 3k, first there's a hiss which I assume is the turbo then comes the whine......any suggestions, advice? I haven't yet had a listen directly, with the bonnet up but I now have paranoid fears of turbo bearings being shot and other such serious stuff...
