turbo oil filter

["Daniel R. LeFebvre" <danbu99@bu.edu>]

hi,
        getting ready to change my oil, and this is the first time i've
done it myself on the audi.  everytime i look up oil filters, the books
always show two numbers, one listed for "engine" and one listed for
"turbo."  these are both listed under the 5000 cs turbo model.  are
there two separate filter replacements that i must do?  thanks.
