I have a 2005 Pt Cruiser Turbo. I have noticed lately that the turbo makes a whine down noise even if you let it idle for a while then shut the engine off. I have not heard this before. I would expect a noise upon acceleration. The noise lasts about 20 seconds. Anyone have this experience???:o

i have an 87 csx, and hear whine down noise quite a bit. it's usually more pronounced if i've been driving it pretty hard, and then shut down (after idling a bit for the bearings to cool some).

FWIW - i've heard that noise plenty of times on the car, and the turbo lasted 20+ years. just had it rebuilt this year. (also always used mobil 1 synthetic)

It's not the turbo, it's the fan. My 03 PTGT does it too and for FWIW my fan needs to be replaced so that might be something to look into.
