[200q20v] Leaking hydraulics; not a hose or the rack.

The pump rebuild was my first DIY repair on the '91 200q. I bought the
"standard" rebuild kit from Carlsen Audi. The leak in my pump seemed to be
from only one of the slotted caps--on the top side. I replaced all the
internal seals and all the o-rings beneath the (slotted) caps. I gave up on
reaching the o-rings that are beneath the two allen head screws (check
valves?), which failed to loosen despite a couple of evenings of assaulting
with impact tool, pentrating oil, etc. Also I did not replace the seal on
the drive shaft. It's now been a couple of years, and the rebuild is still
quite drool-free.

Removing the pump was easy--well under an hour, and the reinstall is also
under an hour. But the work done "in between" can be quite variable
depending on luck (or lack thereof).  I spent hours fruitlessly whacking
away at those two allen head screws. I also gave up on the drive pulley
removal when I realized it would require much more of a gear-puller than I
had available. Replacing the (8?) o-rings under the cross-slotted caps go
rather quickly (10 minutes each?) as do the little o-rings at the interface
of the two pump "halves". The only special tools needed are impact wrench
and a 3/4" drag-link socket. Oh, also (theoretically) an Allen driver
(maybe a few of them) and a gear-puller if you decide to replace the
driveshaft seal.  If your time and capacity for frustration are limited,
you might just want to install a rebuilt pump. On the other hand, the DIY
rebuild only involves risking about $25 and an evening's time.
