Hey guys
So im having the 'old thermo fans coming on when the car is off'.
Firstly my car is: 2009 S3 3 Door
Backstory is: It started happening out of the blue about 6 weeks ago....
I came here, searched around, others seemed to have similar problems, except in mine, both fans were coming on full speed, which, the solution seemed to be, the fans were on their way out.
Easy, go down to my parts place, pickup a secondhand fan assembly from a car with faily low k's.
Wrong, i installed and the problem continued.
So it ****** me off for a few days because the day it started happening was the day i was to flash my first tune...
Few days went by and i wanted to get to the bottom of the problem but i had the far fetched idea that MAYBE the tune somehow magically would stop this from happening.
It did and i was of course more than happy..
So that was 5 weeks ago and id completely forgotton about the damn fans when it started happening today again.
No sweat, ill fix it up, ill reflash the tune itll go away for sure.
Nope, it did not.
btw when the car is running, the fans work as they should, they come on and turn off as they should - they work normally.
which is why - i assume - that VCDS has reported nothing - before, after or now, and i run it quite regularly. And i suppose why would it? When the car is on, which VCDS must be to be run, things are peachy..
So whats my next move here? Coolant sensor? I dont wanna do it unless i have to, i cant even find it in where its supposed to be, it looks like an ******* job, but if it must be done then it must.
Cheers for any input and in the meantime ill reinstall the switch i made up to kill the fans when im not in the car.
