I have a '96 TA WS6 with a 6 speed. The car has a little over 40K miles on
it. When the car was only a few years old I got a SES light indicating a
bad EGR. The Dealership replaced the EGR and the light went away.
Some time later, the light lit again with an EGR failure. The dealership
said the EGR valve was working fine. They worked through their series of checks
to determine the issue. They finally came to the conclusion that the
passageway within the intake manifold that passes the exhaust gasses to the
EGR must be plugged and that the intake must be removed and "boiled out"
to the tune of $500. I have a hard time believing that any passageway would
be plugged on a car with only 30K (at that time) miles on it. I don't run
any cheap gas in it.
When I decided to pass on the $500 fix, one of the mechanics came out and
loosened the rubber hose between the MAF and the throttle body and emptied a
can of Wynns engine cleaner through the engine. We reset the computer and
guess what? The SES light did not come back on. If the passageway was
truely blocked, I don't think the engine cleaner would have "fixed" it.
A year goes by and the light is back. Again it is an EGR failure.
I run a can of Gumout Concentrated Gas treatment through a tank of gas and
the light goes out and does not return.
Another year goes by and the light comes back. I run another can of Gumout
and the light goes out but comes back on within two weeks. I tried another
can of gas treatment but the light seems to be staying on now.
I kind of suspect a sensor rather than a plugged passageway.
Does anyone have a suggestion as to how I should proceed?
What sensor would trigger the SES light to indicate an EGR failure?
I have forgotten the actual error code. I can stop by auto zone and scan it
if need be.
BTW, the engine seems to run just fine and I passed smog two months ago
with flying colors. I figure that if the EGR passageway was nearly plugged,
there would be some indication in the smog test results. As it was the
pollutant numbers were WAY below the allowed numbers. I took it in for the
bianunnual SMOG check during the two weeks that the light was out.
