Marat,

I am planning to replace the hydraulic pump in my 87 5000 TQ as well.
The slow fluid leak is getting worse now. I am interested in any info
as well. PAP (800-944-2964) has a special sale (till Oct 31) on 84-88 5000
remanufactured hydraulic pumps for $179.95. The part number listed is
034 145 155 X 88. Don't know if it'll fit an '90 100 or if it is the new
design. May be you can call and ask. My local Audi dealer has the pump
for $301 and claims its the new design and comes with a 1 year warranty.
