Just bought a 90Qs 20V with a "few" issues.

Hi guys,

I just bought a beautiful '91 Audi 90Q. It has every option but came for a
low price due to a bunch of minor issues.

I have driven the car bout 50 miles now and I got a list of questions/issues
that I hope the group can help me with...

#1 Driver side door lock does not work. I hope that this is the same problem
as described in this article:

#2 Engine coolant gauge does not seem to be working - it is always showing
low. However, at the same time, the car heater is not very hot. The radiator
and engine get *warm* but not as hot as I would expect. I bought a new
thermostat - something tells me that the one in there is stuck open...

#3 The oil temp gauge is also showing 60c and does not move. I refuse to
believe this number - must be broken - please instruct how to test/fix.

#4 Driver side rear window does not roll down. Please advice on common
causes.

#5 Driver side headlight cracked - please advise a good source for a
replacement. Are there any improved "euro" or other headlights that I should
look at getting?

#6 One of the foglights is also cracked - where should I get it?

#7 I might need to post a picture of this as it's hard to describe...
Between the front bumper and the grill there is a molding stripe that is
held down by two screws located behind the headlight washers. The covers
that go over these screws are missing - where do I get them?

#8 I own a pair of Audi 4000's nether of which I have driven much lately. It
may be that I am just spoiled by my VR4 daily driver (Dynoed at 380hp 420tq
on the ground), but My Audi 90 is feeling a bit under-powered to me. The
engine feels and sounds strong, but the power is just not there... I checked
the air filter... Seemed ok... I have driven a 90 a few years and I remember
it having quite a bit more power... Any ideas?

#9 It seems that by design, the rear diff lock disengages at a certain speed
around 20mph. This is very annoying! I would like to keep the diff locked
when playing in the gravel at 60-80mph. How to I override this "feature"?

#10 The E-brake completely does not work. When pulling the handle, I feel no
resistance. Common possible issues?

#11 The Oil pressure gauge gets pegged at 5BAR at around 3000RPM. Is this
normal or is the gauge not working properly? The gauge response also seems
very slow. I have Greddy gauges in my VR4, which seem to react much more in
tune with RPM.

#12 Again, maybe I am just not used to it, but this motor seems to have an
issue with running momentum - as if the flywheel is REALLY heavy. When
hitting the clutch, it takes it quite a long time to rev down. I am used to
downshifting when getting off a freeway or coming to a red light. In this
car it does not work so well as the engine tends to want to keep running and
does not slow the car much for 2-4 seconds... Is this normal?

#13 The back of the passenger headlight seems to have a hose that leads to
the header heatshield. Could someone please explain to me what the heck this
is and what's it for?

#14 Although they worked on the test drive, my high beams do not work at
all. When turning them on, the low beams cut out and I have no light.
Tapping the passing light switch does nothing. I will check fuses and relays
tomorrow. Any description of where to locate them would be of much help...

#15 The driver side front seat has seen better days. What's the solution? 

#16 I already bought the car, but I would not mind having a CarFax for it.
Does anyone have an account?
