I am a little late with this, but I was also looking for bobbins for my Pfaff Expression 2.0. I found this information in the Pfaff Accessory Catalog 2012:
You can view the catalog online here:
http://www.e-magin.se/v5/viewer/file...?gKey=jj61b7rh
Page 6 shows that a Pfaff Expression 2.0 is a code letter "J" (any accessories listed with a "J" will work with this machine)
Page 27 lists bobbins for "J" machines as: 820921096- 10 pack grey and 820905096 - Monet bobbins 20 pack
I was only able to locate the gray 10 pack online.
Hope this helps someone.
