[urq] [s-cars] ATF fluid in the reservoir : What to do?

[Eric Renneisen]

Your description (especially "serrated nut on top") indicates this is
the hydraulic assist reservoir.  ATF in there is the originally supplied
fluid (Dexron II, I think).  Audi superceded the ATF with P/N G002000,
which we all know as Pentosin (first 7.1, then the synthetic 11S), when
the later cars came along.  I've heard that the higher pressure systems
in the type 44 required the new fluid.  It worked fine in the urq, so
they just specified it for everything rather than having to keep both
ATF and Pentosin around.

I've seen various recommendations for switching the fluid, from "just
use whatever's handy," to "don't ever mix them."  I run Pentosin 11S in
mine, mostly because I have it around for the S4s and former CQ anyway.
I'd say you're fine with the ATF.  Your brake problems lie elsewhere,
possibly a siezed caliper from non-use?

--------  It is the black/dark cylinder mounted on or close to the
firewall, with one round/serrated nut on top.    There is one (or 2?)
master cylinders just above the drivers footwell area but inside the
engine compartment .   One has a little rectangular fluid res.  , I
checked it too and it has green/blue color fluid.   I guess  the ATF has
not gone everywhere, maybe? ?    So, if that be true, then maybe I won't
have to rebuild/replace All the cylinders .   ...Thanks,         ...

  Stephen:

  ATF in the BRAKE Fluid

  or ATF in the power steering reservoir?


  BIG difference!
