Hi, could someone check what temperature the fan kicks in on the S3? In particular if you have a pre-facelift (just in case there is any difference between pre & post facelift!).
You can check the temperature by using channel 49 on the air conditioning console. Just get the engine warm. Park it up and wait for the temperature to rise, pop the bonnet and see what temperature the fan comes on at.
This thread here has some info from ELSAWIN on the temperature that the fan should kick in at 8l s3 air con fan not working help
My fan was only kicking in at 104C and apparently the signal was going to the fan to kick in at Stage 1 but it the fan wasn't starting. So it seemed my fan was gone.14 -
Radiator fan thermal switch -F18-
Switching temperatures: Stage 1 on: 92 ... 97 °C/ off: 84 ... 91 °C
Switching temperatures: Stage 2 on: 99 ... 105 °C/ off: 91 ... 98 °C
I replaced the fan. Now the fan kicks in at 99C and cuts out at 98C.
I was expecting my fan to kick in somewhere between 92 - 97C.
This seems quite odd. The fan doesn't control what temperature to kick in at from what I have read. That is controlled by the fan control module. So simply replacing the fan should not have any affect on what tempature it kicks in it? But it has in my case. Previously on the old fan it kicked in at 104C, whilst now it kicks in at 99C.
Why has the temperature that my fan kicks in at gone from 104C down to 99C by simply changing the fan?
Does it sound like my fan was never broken? Because it is still not kicking in at Stage 1.
