Solved A Cooling Fan Is Turned Off When It Is Running At 800 Chegg Replace the ecu cover if it is compromised in any way. on some models, like mine, there is a metal clip which bridges across the ecu itself. push down on either end of it to release the clip. you can then lift the ecu out of the way which will reveal the 219 fan control relay. note the evidence of water in the ecu box from the settled orange. Interesting but not necessarily true. my kids 2015 a4 fans do not stay on after shut down unless it just was shut off in 95* temps . even a 50 mile run at 75 mph the fan shuts down at turn off. the other part of the problem is that the fan turns on even with a cold engine when he turned the engine on. he is trying to determine why this happens too.
Solved A Cooling Fan Is Turned Off When It Is Running At 910 Chegg I think you've solved this issue before. the primary cause of this problem is water inside the ecu box. the water leak fills the box and shorts out the relays inside. remove the cover and check for the presence of any water inside the ecu box! vorsprung durch technik. When ignition is turned on or engine running, the fan will run on full speed regardless of whether car is hot or cold after been left overnight and continue running. on turning the car off it will run for just under a minute then stop. a scan of the car revealed fault code p0480 indicating a fault in cooling fan 1 control circuit. It maybe necessary to start the engine and then shut it down, wait a few seconds and the turn the key back on and re select the [output tests] if the tests do not run or you want to run the tests again. hope this helps, drpeter. uwe, jack@european parts and 2stroke. ( 2008 ) audi a4 "b7" i want to force drive the external cooling fan with vcds. When your a4’s a c is blowing warmer than the outside temperature, it strongly indicates that the blend door actuator is causing the cooling issues. here’s what a bad blend door actuator sounds like: sometimes, it may come off as a fast and lighter clicking sound. cooling fan. a defective cooling fan will cause your a4’s ac to stop.

Your engine temperature sensor is responsible for relaying your engine temp to the ecu. once the temp gets so hot, the ecu commands the radiator fan to come on. if your a4 has a bad engine temp sensor the radiator fan won’t know to come on, because the ecu won’t know how hot the engine is. you’ll need to locate and test the engine temp. 1. jul 21, 2017. #1. hi everyone, i have what seems to be a common problem which is my radiator fans won't stop running, slowly, (both of them) even with the ignition key off and the engine cold and air con off. (if i try to turn the air con on the econ light stays on and i'm unable to turn econ off.) but i don't care about the air con, all i.
