Air conditioner adjustment in 4000 Quattro

[Tony Hoffman]

Fellow Audi Guru's,

I searched the Archives, and can't seem to find the info I"m looking for.

I'm working on the A/C in my 4000 Quattro. It got very weak, and so
now I've cleaned the expansion valve and I'm also replacing the
Reciever Drier. Those two things plus cleaning the lines as I have
will fix my basic problem. However, while I'm in there I wanted to
check on adjusting the A/C for the coldest temps I can achieve (I'd
like 34 degrees at teh evaporator). I recall reading years ago about
some sort of adjustment, I was thinking it was on a 4000Q or Coupe. If
anyone knows of this, and where it is located, I"d love to know. I
only see the expansion valve in there, and there isn't any adjustment
on it that I can see.

As always, thanks in advance,

Tony
