Can someone help with this, please? There's something wrong with my climate
control ('96 A6), and I think it must be a sensor or relay problem. The
compressor itself and the fan are both working fine and the system produces
plenty of cold air, but only with the system set to "Lo". If I set it to
"18" or above, the system (usually) works OK for a time, but after a while
it starts to blow out hot air even in outside temperatures of 25 degrees or
more. Consequently I have to set it to Lo all the time and just adjust the
fan speed manually, which is far from ideal. I'm not sure where to start
looking for any obvious defective sensors or relays.

Hi!

[Cool air on LO only]

Go to

Check channel 56 and 57 of the climate control unit, these
should represent the inside temperature measured at the
interior light and with the sensor in the dash (in °Celsius
AFAIK). If that shows "too cold" values compared to the real
temperature one of the temp sensors or its wiring is faulty
and make the CC think it should heat.

Check channel 01 for error codes.

Unfortunately,

http://www.12v.org/maint/cc.html

is out of service currently for a more elaborated code
listing. You can use

http://home.arcor.de/ero.rademer/oth...-codes-62.html

as a backup for now.


So long!
Ero.

Thanks very much.
