new to Audi, new to the list

[Drew MacPherson]

Greetings to all.  I recently acquired an 89 200 Turbo Quattro Avant.  The 
car has a few mechanical issues, so far nothing major, and the body and 
interior are in fantastic shape.

My goal is to have a nice reliable "family" car for my wife to drive.  
The Bentley factory service manuals are en route as I type this, and I'm
engaged in the process of clearing Volkswagens off the shop floor so I can
begin to work on this substantial hunk of German steel.

I have two specific questions that arise from my cursory examination of 
the engine bay and/or the history of the car provided to me when I 
purchased it.

1) the after-run coolant pump has been "deleted" - I'm guessing because it 
may have developed a coolant leak.  I understand that this pump circulates 
coolant after shutdown in conjunction with the cooling fan to cool the 
waterjacket and the (water-cooled) turbo.  How frequently does the 
afterun cooling system operate - is it only after "spirited" driving with 
hot ambient temperatures, or is it pretty much any time the engine has 
been heated to operating temperature and the ambient temperatures are 70F 
or greater?  Is there a good (read: inexpensive) source for these pumps?  
I do not have the old one, so rebuilding is not an option.  My immediate 
area is (painfully) devoid of any Audi parts cars of this vintage, however 
I may be able to find something a little further afield.

2) the hydraulic pump is leaking - in persuing the archives I've learned
that this is not uncommon.  There is a rebuild kit (or a few o-rings and a
seal, anyways) available from the dealer for around $50 CDN.  Has anyone
successfully rebuilt their hydraulic pump?  I understand the procedure is
detailed in the Bentley (which I hope to have by the first of the week)  
but I would appreciate any advice based on personal experience that can be
offered, as the alternative is a $250 CDN rebuilt unit.

Thanks in advance for any advice/input offered.

Drew
