What is the proper Bosch oil filter for the 2.1 l WBX?

Reason I ask, is I got one from my local favourite VW parts store, and
it didn't list a Bosch, so they ordered in a Mann filter (# W719/12),
which is a good filter, but it cost me $16!!!  The local FLAPS (not VW
shop) says the filter for my 98 4-cyl Golf (Bosch # 72150) is also for
the Vanagon.  I don't believe that (but it would be nice since they're
only 5 bucks each).  The filters (Mann and the Bosch one for my Golf)
look the same, and are the same size, but other than that, I'm not going
to say they're the same!  I saw somewhere that the proper filter is a
Bosch 71028.  Is that correct?

Help the kid out!
