[s-cars] Help! - Auxiliary Water Pump

[JR]

Anyone know where I can get a new one of these (Part # 034 965 561 C) in
a hurry?  I need is ASAP as my car is stranded.  I will pay overnight
shipping!  I'm a bit confused as a search for them on the internet.  The
part number appears to be the same part used in a variety of Audis and
VWs.  In particular it appears that the 12v VR6 VWs and the URS4/S6 use
it.  When I search for it for a VW 12v VR6 it comes up $40 cheaper than
when I search for the exact same part for an 93 Audi S4 on the same
website.  Again, part number is the same!  What's up with that?  For
example:

http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi/?html=learnmore.html&productID=4232

Notice that the models it can be used for are the same in some
instances.  I don't get it.  Are they just trying to charge more just
because you want it for an Audi?  It isn't just ECS.  It's other sites
too.  It's cheaper when you search for a certain part for a VW than when
you search for the same exact part (same part # and everything) for an
Audi.

Thanks,
