Whine on cold start.

    I have a 2007 PD170 Quattro that makes a whine on cold start for maybe 1/2mins then stops.

    The noise itself doesn't fluctuate with engine RPM, I did wonder if it could be the clutch release bearing but it doesnt change in pitch when the clutch is depressed so doubt it.

    I just replaced the EGR cooler that has been cracked at the exhaust manifold end for a while, I assumed the noise was maybe related to that but it's not.

    Ideas?

    Could be your air con pulley mate. Once warmed up it stops. My car did the same and that's what it was.
