differential leak; pressure accum.

[dhowitt@iddis.com]

Hi again, opinions requested:  

1. My '89 100q rear differential has a slight leak.  An Audi mechanic told me 
to leave it alone -- just check the level once in a while -- that most of them 
do this but they don't leak very much!  This surprised me -- Is anyone 
familiar with this syndrome and with this advice?  Dealer says it's about a 
300 USD repair.  Checking the level is a nuisance because one must remove a 
heat shield to get at the filler plug, and even then the plug is hard to reach 
(I think there's a special tool for it).

2.  I need a brake pressure accumulator.  The dealer quoted about 350 USD for 
the part and an hour of labor to install.  Is there any point looking for a 
cheaper alternative, i.e., non-Audi part or used part?
