On every setting but ECON, my *HIGH* speed fan will run.

I cannot under any circumstances get the 1st speed fan to run.

Use  your coupe bentley to troubleshoot the climate control, section D8,
starts on  D8-140 (D8 is right after group 74 if you can't find it).  Low
speed should  work with climate control in any setting except ECON, while
outside temp is  above around 40 degrees, and key to ON, whether engine
running or  not.

Tried that LONG ago.
Doesn't work.

My bigger  problem (which is most likely related) is that the 1st speed
fan does not come  on at all.
I'm going to tear into it  this weekend.

After run  circuit is pretty easy to troubleshoot on all the turbo  Audis.

First step:  engine off, look  at the coolant rail on the radiator side of
the head.  There are two  temperature sensors on it; the smaller 2 pin
unit is used for  afterrun.
Connect the two wires together (don't let them short to ground)  and
you'll have the low-speed fan and pump run.  It can be hard to tell  if
the after run pump is working; it should vibrate, but that doesn't always
mean coolant is flowing, as the impeller may be  frozen.

Hmmm, it can be made to  work.  I have a 4-row Al
radiator (from 2B, bought it years ago when  the
stocker broke, before they raised their prices) and
no AC.  The  thermoswitch on the rad. does it's thing
switching the fan on and off, and  presumeably the
thermostat is in good working order.  I have to  really
work it to get the oil temp guage  above 100C  (stock
200tq/3B oil cooler) and the VAG-COM shows group 000
engine temps  right around 200F as it should be.
The only issue I have is that I have yet  to hear
the after-run fan/ pump kick in.  I understand that
is not  unusual for 3B/ AAN cars, but I still plan to
dig into it at some  point.
Net I think the only components that could cause your
trouble are  the thermoswitch and T-stat.  I would be
surprised if the stock  radiator is really that
defficient.
