Re: Climate Control System Making Noise

I noticed the same noise on my A4 too.  In fact, just last evening as I was 
pulling out of the Audi service center I noticed the noise, so I turned around 
and pointed this noise out to the service person.  He had not observed this 
noise before.  Since it was late in the evening (~6pm), he said he would have 
the technician look at it when I take my car back to have my lock replaced 
(that's another story).

This is what we thought was was the cause of the noise:  the Auto system diverts
air between different vents by moving motorized flaps.  The noise is related to 
the flap movements that occur as the system tries to stabilize the air 
tempature.  It goes away after a while as the temp get even.

Bottomline: the noise is probably not a serious defect and you could wait till 
your first service.  If my parts arrive before that, I will take my car in and 
let you know what the service technicians think.

Subject: Climate Control System Making Noise

Befor getting to the details let me point out that the following problem is
ocuring on a three week old Audi A4 Quattro.  Thus the reason for my concern!

On to the problem.....  A 'rubbing'/'whiring' noise is coming from or near
the passenger side air vent.  I know that the problem is related to the
climate control system as when I change the settings and/or direct the flow
through that vent the 'rubbing'/'whiring' noise becomes more/less
pronounced.  Before I go to the Audi dealer bright and early tomorrow
morning (the Audi gods should know that I need sleep after working a 75 hour
week) I would appreciate responses to the following:

1.  Does anyone have any idea what iscausing this problem?

2.  Does anyone have any idea how I can solve the problem?

3.  Is the problem sever enough that I should go to Audi tomorrow AM rather
than wait 2 to 3 weeks when the car will be going in for its 1000
mile checkup?

4.  Any additional advice/comments beyond the above questions.
