Climate panel controls rad fan....

[RS2 driver]

Hi

Have noticed kind of strange behavior with the radiator fan.

My RS2 have Auto climate control and when the A/C is turned on the radiator fan run as it should, fan also cut in when engine temperature reach approx. 95 deg.

However it is also running when the A/C is turned off AND the temperature in the cabin panel is adjusted above 19-20 deg OR when the cabin fan speed is raised above stage 3-4!
The car had an A/C service with refilling and leak test of refrigerant last year without changing the behavior of the system.

Have anyone experienced similar problem with the A/C/climate control on the 80 series or have a good guess of the cause?

Hi.
The climate's secret menu have some options.

Maybe we must put a list with ours parameters and compare.

PD: I tthink that the chanels are 14, 15 and 16. I don't remember correctly

does the fan turn on together with the compressor clutch? that would explain the fan and we should look to a problem in a different perspective - i.e. why does the a/c start.

If not, it is really, really weird.

On mine the fan is not only turning on with the A/C compressor.
It seems to be "controlled" by temp setting and cabin blower setting, when one or both of those are increased the radiator fan comes on.
However when the A/C compressor is turned on the fan is also running.

Very strange behavior

Not sure about the hidden menu`s of the climate panel, how to you get access to this?

My fan on rs2 also turning all the time when the climate is on, A/C on or off has no diffèrent. These list is for a A4?

when i turn on the ignition key and the climatronic activate, the radiator fan also works, on LO until HI makes no difference she always turn with a cold or hot engine. also the little star for AC turns off when the temperature is below 7° degrees i can't turn it back on. When the temperature rise it works again.
someone can explain this? sorry to hack your topic...

Mine too and I prove with 3 climate modules.
