acc to my 1998 family album the ECT should be located on top of cooling
water manifold outlet from right cylinder bank (left side when standing
in front of car). So if this isn't changed on the 2001 model you should be
looking in the correct area.

but acc. to the article

it's not easy to spot, and change either
hope this is of any help...

Thanks. I know when to give up... I had looked at the link you
provided already and found the one sensor, but was unable to find the
blue one...Audi had to have moved it from the link you provided,
because I was looking immediately underneath the hard plastic piece
and there wasn't anything there.

I called a small independent shop in Denver and they are going to look
at it on Tuesday....he said when that code comes up, it could also be
the thermostat...so, rather than me changing parts that might not need
to be changed, I will just take it in.

If it is the thermostat, then you may want to consider splurging - and I do
mean splurging - for the T.B., water pump, tensioners, etc if it has been
more than 50-60,000 miles since that service was done.<!-- ~MESSAGE_AFTER~ -->

I am new to Audi's (been driving Japanese cars for the longest
time)......there must be a TON of labor involved in replacing the
thermostat??? When I replaced the thermostat on the Japanese cars, it
was usually pretty easy, I am guessing the Audi's aren't.

I can already $ee the cost ....... thanks for the tip...... the car
has 55,000 miles on it and I planned to keep it to 75,000 miles. At
that time, I plan to trade it on the 2.0L A4 coming out this
Spring...I want to give Audi a chance to work out the bugs before I
buy that one.

I let my T.B. go until 73,000 miles. My '98 A4 V6 2.8 has a 90,000 mile
interval in the maintenance manual but I believe Audi has reduced that
interval since. When I had it done I also had the water pump, thermostat,
tensioners and serpentine belt replaced and oil leaks fixed to the tune of
$1200 total at a good independent. I think the oil leak portion of that was
about 1/3. I believe the labor for the thermostat is almost as much as that
for the T.B. because you have to do much the same work to get at the dang
thing. I suspect you'll find that problem is the sensor since it seems to be
a common replacement item. Ironic you should be coming to Audi from
Japanese, I expect to be going in the opposite direction in a year or two.
I've had Audis for nearly twenty years so time for a change. If you haven't
done so already, you should check out Audiworld.com. There's a wealth of
info in the searchable forum archives.<!-- ~MESSAGE_AFTER~ -->

Whan I bought my A4 2.6 towards the end of 1996, I remember the dealer
telling me that the introduction of the 2.8 30v was delayed because of
the significant number of belt failures in testing, before 60k!

Indeed - but if they struggled to reach 60k reliable miles, I wouldn't
trust it much beyond that distance.
