My 05 diesel vectra has developed a whining noise. It increases under acceleration and decreases when you lift off. It only started after the car was not Pulling through fuel over 2000 revs in any gear, I floored it and it seemed to clear it but then the whining noise started. The first problem I think was dirty fuel injectors, have cleaned with redex but whining noise persists!!! Anyone have a clue of what it might be?

If it was a belt the noise would be progessive with the engine rpm. However the op implies it worsens when on the throttle and backs off when he is off the prottle pointing to a turbo or boost pipe problem. Regards Peter
