[urq] Could ATF Dexron II eat diaphram pressure accumulator? (akabomb)

[Ashley Cobain]

When I had my rack reconditioned I did a lot of research and asked lots of
questions (some on this forum) because the rack came with a warranty that
said it was only covered if the green stuff was used - and previously it had
been using the red. But the definitive advice came from Scott Mockry of SJM
autotechnic who said that green following red is OK provided you flush out
the red as best you can (which means wasting some expensive green). But red
following green is a no no. I followed his advice and all has been well
since.
Hope this helps
All the best

> As we all know, Audi used red ATF Dexron II in the earlier cars and parts
like the bomb, pump and steeringrack which where designed for this kind of
liquid. From 1988 on they 'upgraded' to the green oil and changed those
parts accordingly.

> It's been a known fact you cannot use ATF in those 'newer' parts because
it would 'eat' the seals but it is supposed to be safe to use the green oil
for these 'older' parts original designed for ATF.
>
> My first question is if we would buy a new steeringrack or -pump and
pressure accumulator (aka the bomb) from Audi today, will those be designed
for the green stuff -only- and therefor not to be used with the red ATF oil?
>
> I ask this because I'm still having the ATF oil in my car and when my bomb
was replaced last year with a new 'cheap' OE type from FEBI (BMW 7 series),
and it only lasted a few months. A few months back I've put in a used bomb
(not sure if the previous owner used ATF or the green oil in it) but this
one has gone bad also.... Coincidence?
>
> If i would order an expensive original Audi bomb today, will that be
designed for the green stuff only and will it be destroyed when used with
ATF like the other two?
>
> In other words, should I better 'upgrade' to the green stuff this time
when I replace the bomb with the Audi part or could I just keep using the
ATF oil?
>
>
> I hate this part of ownership when they (Audi) switched fluids and sell
'upgraded' parts which are not compatible with older parts and fluids...
