Re: Some newbie questions on a regular '91 100

Hairy green toads from Mars made Tak Cheung say:

I hope the others still have good homes, and have not met
violent or untimely deaths ;-)

I can't answer some of your questions, but have a few things
that might help you.

This could be the dreaded "recirculate flap" problem. My Climate Control
(in an '89 100Q) does just fine keeping the windows clear at 0 degrees
with a car full of people. The flap is located somewhere behind the
glove compartment. I believe there is something in the FAQ about this.

Your explanation could be correct. One way to check for leakage is
to crack the sunroof open (by tilting up the back) just a bit. If
the noise around the windows gets worse, you have leaky weatherstripping.

My '89 makes a little wind noise, but it's pretty quiet overall.

YUK!!!!! Don't get P500's! I made that mistake with my old Golf,
and Mike La Rosa recently made it (against my advice ;-) on his
100Q. The P500 is a marginal, mediocre tire. Poor traction,
poor dry handling, and fairly noisy. Not that cheap, either.

The Dunlops would be better, but I highly recommend the Goodrich
Comp T/A VR4. Get the "V", not the "H". There's a big difference.
They cost about $100/corner.

> (5) Why is '91 100 on the Consumer Report's Used Car to Avoid list ?? :)

Because they need maintenance (all german cars do), and American drivers
don't maintain their cars properly. This makes for $$$ repairs a couple
of years down the road. Of course, we know that Audi's never need
any $$$ repairs, don't we?

Seriously, Audis need specialized work, much of which can't be
handled by your typical corner garage. You need a good mechanic,
and the help of a mailing list like this one.

Only my cat shares my opinions, and she doesn't make any wind noise.
