I had the same noise as you do. About 5 min of loud grinding noise.
1. I changed the top pulley and switched to the short belt. (Noise remained)
2. I took to dealer to diagnose noise on a cold morning start. They said it was coming from the purge valve (which is opposite of the belt tensioner), and the purge valve hose was cracked at the TB.
3. The purge valve costs around $200 Can and hose is $7. I ordered the hose only.
4. Now the funny thing. Ever since I got the car back, the purge valve (noise) has been all but gone. I can hear it faintly on some mornings but no wear as loud as before. I assume they fiddled with it.
5. I also replaced the purge valve hose. That's another story ( http://www.saabnet.com/tsn/bb/NG900/index.html?bID=98349 )
6. Not planning on replacing purge valve as of yet. It is a very easy DIY job.
7. Not sure if it is the cause of the noise. But maybe it's a good starting point. Maybe you can tap on it when it's making the noise (careful of belt). Also check purge valve hose for cracks (this is what caused my idle to sputter occasionally).
Hope this helps. Let us know what you find out.
