Might be the air pump in the front left of the car. Sounds like a high pitched whine and lasts about 2 minutes. It will only come on at engine start with a cold engine.

Well this might just be the simple fact that, during cold starts, the engine revs higher for a few minutes just to get the car "warmed up", and so your idle is around 700-800 RPMs more...
After a few minutes, it dips back down to a normal idle.
Maybe that's it.
