2007 Audi S4 Base 8 Cyl 4.20L
Fan keeps running after vehicle is turned off
I have a 2007 audi s4 base 4.2 v8 and when I turn the car off sometimes the fan will continue to run. It may run for 20 min or so sometimes causing the battery to die. It isn't overheating or even running hot. Is this a common problem? What can I do to fix it?
There are several possibilities; faulty cooling fan temperature sensor, faulty cooling fan relay, faulty cooling fan wiring or connections.
