Hi Max;
Well, you've found where the spring should be attached. Now you need to get
a spring and hook it up so the door will stay closed. I'd say you've also
found the cause of your fogging problem. The original spring should be in
there somewhere - it can't go very far.
Merry Christmas!

Disassembly:
I have taken away the glove box, had to use a flashlight to find the 2
Philip Screws which were on top of the glove box, then I removed a plastic
cover with insulation on the top, this plastic cover is held on by a nut on
the right to same frame bracket which supports right side of glove box + a
Philips Screw on the left screwed upwards, easy to remove. I then saw what I
assume is the recirculation flap. The evap coil visible behind recirc flap.
Vacuumed out leaf and dirt debris around evap coil.
What is this black tube like thing hanging on the left in front of evap
coil?
I removed the recirculation flap unscrewing 2 long Philip Screws left and
right. the insulation in front was intact but there is a spongy molding
around the back edge which seems to have shifted. In the middle of this
recirc flap there is a round plastic piece 4 cm in diameter with a rising in
the middle with a hole in it. I think there is the spring that should be
attaching this part to the air recirc servo Cannot find this spring. I
removed recir flap and cleaned it. Will put on similar molding.
When I feel in behind recirc flap in front of evap coil I feel this round
gadget which is moving but not removable, making a hollow rubbery noise. I
think this is the air recirculation servo. What do I do next?

I received this as a good answer:
Your recirc flap actuator is probably broken. This is a very well
known problem with type 44 audi's, and is pretty easy to fix. To
check, remove the glove compartment, and, with the car running, and
the heat on, look up at the recirc flap. It should be pulled up,
sealing up the opening into the interior of the car. What happens
though is that the mount for the actuator brea! ks, and the door stays
in the recirc position all the time. I think the dealers have a kit
to fix this, but I did my own fix. It happened so long ago now that I
don't remember how I did it. Also, I hear sometimes the spring breaks.
Also, if you use the audifans.com web site, you'll probably find a
more detailed write up on this issue. Many people have had this
problems. I'd say almost all type 44 audis experience this problem at
some point.

Max,
can't wait to see what you get for responses... I just bought a 1990
100 (very similar system) for a new driver in the house and have the same
issue. From past experience, it's always been either sucking moisture, as in
a pile of leaves/crud stuck in the intake, or no fresh air intake.
I did clean a pile of crap out of mine, which seemed to help a little
but I'm pretty sure the real problem is I have a flap inop somewhere. I
haven't had a chance to get a good look but I don't have an obvious "fresh
air" or "recirc" bottom so I question how you get fresh air when temps get
below freezing if they rely on the a/c system to get the moisture out. No
surprise my a/c is also inop..! .. hmmm coincidence ? 8-)

Hello All!
I have a 1986 Audi 5000 Quattro 4 door, the heating works, it
becomes hot inside car, though the windows can fog, especially in the back,
and fogs faster when there are more people inside the car. The rear defogger
functions, when degogger is turned off, the back light will fog, turning the
defogger on again, the back light will unfog. The windows have been tinted.
When turned on to "Auto" the vents on the left and right edges of the dash
will unfog side windows in the front, better that center vents be turned off
to have more air exiting from the edge vents. At times I am driving with a
very warm front cabin with temperature showing "HI" with outside temperature
of -4C but with foggy windows.
I wonder if the vent like slots behind the! rear speakers below the
back light have any role in this issue of windows fogging. On the outside at
the bottom of C-pillar, just behind rear quarter window, there is a plastic
covered section, painted the same as! the body, I can peek in behind this
vent like cover. I wonder if this has any role in the fogging of windows?
Any suggestions to the solution of this fogging?
Max
