Sounds like my 98 T5M. When I let out the clutch I sometimes get
a scarping sound. Not always. Sometimes in 2nd or 3rd gear, too.
I believe it is the throw-out bearing and a couple others have reported
the same thing on this board. One poster indicated a noisy
throw-out bearing is a common problem but that does not mean it is going
to fail any time soon. He also suggested squirting some wd40 down the
actuating arm to quiet it a bit (and said it would not hurt the clutch).
I have not tried Wd40. It has been making the noise for about 20K miles
with no other problems.

Does your's do it every time? I can adjust how fast I let out the
clutch and that seems to make a difference.
