That puller certainly looks like it should do the
trick.  The attachment I use is slightly different. 
The "feet" are cut a little more aggressively, and
there is a screw across the 2 puller feet to
mechanically spread them and lock them in the spread
position.

My original and the replacement from Import Parts
Specialists are the one on the right.  P/N 046 105
313D.  Same maker (Ina), same manufacturer markings as
the original.  $3.00

Joining mine.  Went up for 1-2 weeks, or so I thought.
 That was before Thanksgiving.  My SO has other
thoughts about my priorities of work.

No shame in driving a FWD Audi, IMHO.  There are much
worse sins in the eyes of this auto enthusiast.
