Please bear with me. I'm sorry if this is long.
2000 A4---1.8T---77K miles: Note, I am trying to fix an A/C system so I can
sell my car. $1400 to replace the evaporator is just nuts at this point.
There is a leak in the A/C system that both my mechanic and dealership have
concluded must be in the evaporator core because the dye just isn't coming
However my mecahnic is puzzled by something though: His company repairs
Audi's a great deal and he said that since this car has had several
recharges with 1 leak stopper that targets the O-rings one of which I
replaced and at least 2 of the leak stoppers that is meant for heavier leaks
with dye's both UV and bright red, that he is having a hard time imagining
that even the evaporator core could hold that much dye + stop-leak oil base.
There is no sign of a leak anywhere: clean condensor, weld points,
compressor, lines, etc., etc.
Here's the whack job history:
1. June 2005: Mechanic 1 recharges system with dye.
---> a/c dead nearly right away
2. later June 2005: Dealership sees no dye and recharges with some form of
stop-leak (I think) and dye.
---> this lasts through the summer.
3. April 2006: A/C dead---Dealership recharges---sees no dye----puts in more
---> this lasts maybe a week
4. May 2006: Mechanic 2 recharges the system with a light stop-leak (not the
"gold" type) and replaces an O-Ring and the Schrader valve.
---> a/c dead but took a few days to lose a small amount of coolant. The
coolant is still there at a lesser amount but too low: the low-pressure
switch has shut down the a/c.
6. June 2006: Mechanic 2 is encouraged by the slow leak and refills and
drops in the dye and expensive stop-leak stuff. He lets it sit in his lot
for a few days and it holds pressure and produces very cold air.
---> a/c dead in a few days.
7. July 2006: Mechanic drops in one more strong stop-leak and dye.
---> This is gone within a few hours.
Can you tell me if there is any chance that the problem is not with the
evaporator core? Any other thoughts?
Doesn't /anyone/ know where I can find a credit card company that emails me
the minute something is charged to my account?
