Hi there,

My a6 has started making a noise like a loud fan, coming from under
bonnet not sure where yet. seems to happen when the weathers hotter
and most often when the cars parked on idle. the noise stops when i
turn off the cc after a couple of seconds, comes back if i have the cc
on.

Any ideas what problem could be?

So open the hood some day and take a look. My bet is you're hearing the
radiator fans turning on to take up the extra heat load the cc produces under
the hood...

'00 s4 6spd

 

That is what it is supposed to do. The radiator fan always runs
when the AC is on (and Defrost too)

Hi,

Had the car a couple of years and this has just started happening.
The noise is really loud like an air raid siren (tho' you cant hear it
that much from inside), its loud enough that people have stared at my
car in the street!

I think ill be taking it the dealers, its loudest in front of the
radiator near the air intake pipe. If i switch to ECON the noise
stops too.

yes, the problem is the bonnet cable hitting of a/con fan.... adjust bonnet
cable
