Title: Audi B6 coolant fans ON, when CAR is off Post by: BlackT on September 15, 2019, 06:33:11 AM A few minutes ago I came to my car and hear a fans go ON and OFF. Car is locked and it is off and parked since last night. I discconet ECU, but fans keep working, after I connected ECU again the fans go off.
Then I put my battery on charger, but after few minutes fans again go to full power. Does anybody have shematic for fan control on audi A4 B6 1.8T 2003 BEX?
