2004 S40 turbo. On cold start only (it was in the thirties this am) the engine has begun emitting a short squeak or squeal AFTER it has fired up. It sounds like a dry bearing for a very short period. It seems to come from the drivers side of the engine compartment, but doesn't last long enough to pin point it. My fear is that it is a bearing failing on the turbo. It went away after the engine warmed up. Thoughts?

Thanks,

the Snark
