My girlfriend's car had this same chirp. We had all belts changed as they were about due anyway but made no difference.

I feared it was something to do with the turbo- seemed to chirp more if you got it spooling quickly enough after turning on but I think it's sorted itself out now...

Unless it has something to do with a suspected (and again temporary) misfire presumed to be a coil failing.
