I replaced the polyrib(serpentine) belt but this did not solve the problem for me.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I tried to start with the air conditioner compressor off but that did not help.
My car makes a brief weird screetching noise when I start it in very cold weather (-10C). Almost like there is no oil! Any views on this. Hurts me everytime!
Thanks.
Good thought but it sounds more "internal". Plus, I would think that if it was a lose belt, I would hear the noise again when I press on the throttle, which I don't.
Does it sound like a "devil dog" (very loud screetch) that was just eatin up by your car and only happens for about a 1 second right after engine start?
Damn... That's what I thought it was
I wish I could help more but don't have an answer.
I have had that happen to me 2x this winter and the first time it scared the crap out of me. I had the door open...
I'm replacing my belt tomorrow and only time will tell if that works.

I have experienced this same noise with my 2000 Carrera2, loud whine for a second or two after start up. I replaced the polyrib(serpentine) belt but this did not solve the problem for me. I believe the noise is coming from an air pump which sometimes runs at start up to pump warmer air into the catalytic converter. Some say this is normal for the 996 and others say that it could be a sign that the pump is going bad. Anyway, my car rarely makes this noise and I have come to live with it.
