update on help with a '91 200TQ
 

I just wanted to thank everyone again who had responded to my last plea for
help. I finally got the Bentley manuals for the car, pulled the codes that
were stored, and think (hope) I found out what the problem is. The code was
2322, Intake air temperature sensor. Reading the description, it does make
sense, slight power loss (I wouldn't call it slight, but...), increase in
fuel consumption (never noticed this, but quoting someone from this group a
while ago, you don't buy an Audi for fuel economy). I checked the
connections to the sensor, and everything looked ok (no cracked wires or
anything), so I'm currently looking for a new sensor. I've gotten much
smarterer in the last few weeks, and have searched the web for the part,
couldn't find it listed anywhere, so I've emailed a few places to find out
if they have it, just not on their sites.

Just a couple more questions for now. First off, does this sound like a
reasonable cause for the problem I was having? (engine "cutting out" for a
split second in low 2000 rpm range) Second, the instructions in the book
seem really easy to do this myself, is this the case? Are there any hidden
obstacles I should keep my eye out for? I've never soldered anything, in
this a vital step, or should I practice soldering on some of my excess
computer equipment before I attempt this? Any other hints that anyone would
like to pass on?

Thanks again
Bill

Bill,
Put your eye back in.......
Fixing what the computer tells you is broken is a good idea. Bentley should
have a test for making sure that then sensor is toast - try that. After you
have fixed it, try how the car runs and see if the computer logs any further
problems, and chase them. If the sensor is anything like the one in my '87
5ktq (just located differently IIRC), then changing it shouldn't be too
hard, just use a heat-shrinkable crimp connector instead of solder - a
connection made with solder-only is succeptible to breakage from vibration -
especially a poorly soldered connection.
Cheers!
