We had the serpentine idler pulley start to go bad on our 95 960. In the morning we would get a high pitched sound but it wasn't very loud, just noticeable. It would last several minutes and then go away once the engine was warm and not re-appear until the next morning.

If it's a pulley bearing going bad, there are 5 on this engine. Two each on the serp. belt system and the timing belt system plus one on the A/C compressor.

I highly suggest making sure you check the timing belt pulleys. If you can get a mechanics stethoscope (cheap at any auto parts store), you can isolate the sound fairly easily. If it's a timing belt pulley, fix it immediately!
