Anyone have a pic of Tstat location on 1.8t and can it be done without removing TB?

From what I can see, you have AEB (it's very important to tell...

...guys what car/engine/year you have, while explaining problems.) It's easy to find a t-stat housing. Lay down under your car and look at front driver's (almost middle) side. You're looking for the thing on the picture and it's 15min job (no need to remove timing belt).

1.8T AWM Issues? (planning on a Tstat change as well, ECT Content inside) ...
I am also looking at changing my Tstat on a 1.8T since i was about to post the same question, I'll piggy back on your post.
Mine is an '01 1.8TQ (Avant). Is this a job I can do (changing the thermostat myself) or will I face any issues for this type of engine (AWM)?
So here is some info in case someone else searches regarding my troubleshooting.
<B><U>Issue</U>:</B>
Dash Coolant Gauge shows 1/4 mark. It will not go to the middle. I am suspecting I may be getting degraded MPG (19-20) due to poor temperature info fed into ECU making it think I am running cool and running my car rich?
<B><U>Checks</U>:</B>
I did the HVAC trick - (see Tech Articles, Interior)
<U>My readings were</U>:
49c = 68
51c = 90
<U><B>What I've done</B></U>:
Replaced ECT.
The job isn't impossible, but you need very small hands and some patience. The cost was only $25 at dealer, about $30 with a new gasket and clip (recommended!).
<U><B>What needs to be done</U>?</B>
I understand that I need to change the thermostat next. If anyone has any other ideas please let me know!

if it's an AWM ... it is located behind the alternator... you can do
it without removing the timing belt
<img src="http://pictureposter.audiworld.com/145402/img_4519.jpg">
it's really easy to get to if you remove the swing the alternator down (again awm)
just take the acc. belt off
remove top bolt
pry alternator toward driver fender
voila =)

you can reach it without moving the alternator, take off the air intake hose going to the manifold
then stick the needed allen wrench into a vise grip. you can reach and undo the bolts that way, peek in between the manifold sections. easier than moving the alternator.

yes/no
that is how I did it when i did my timing belt change (your way)
+
it's how we did it on my friends car... it was a bit of a pain even with that TB hose removed.
to release belt tension is sub 10 seconds.
remove that one top bolt for alternator = less then a minute
then you have a nice clear area to work with.
Lately when working on the car i'm trying to get in the habit of working "quicker" versus the way that involves the least amount of things to remove.
I think it is quicker to remove a bunch of little things and have clean and clear access versus trying to work in a tight area.
As well it's hard to get a torque wrench on a vice grip allen key assembly
