2001 Audi TT quattro low speed fan and ac fans dont turn on
Hey guys,
I have a 2001 Audi tt 225 roadster which runs normal temp when driving(88-92) but when idling or sit and go traffic it will slowly rise to 99 or 100 degrees then both fans turn on and it goes down to 93 or so. The fans never run by themselves, or on slow speed. I also tried turning on the ac to see if that would trigger them, and neither fan turned on with the AC running.
What triggers the low speed fan to run, and at what temperature? Also shouldnt atleast 1 fan turn on when I turn on the AC?
Thanks for any help!

Here’s a helpfu video fo VW. Our cars are very similar in function. I’ve replaced the larger fan on each of my TT and gotten them working.
Good luck!

Hey thanks,
I gave that a shot, and when I jump the power to the high speed it works, when I jump it to low speed it doesn't. Would this be a faulty fan control module or a bad fan?

Based on what I know. That would be a bad fan. Low speed resistor burned out. That happened to both of my cars. Apparently fairly common.
