That fan is to cool the engine. It is normal for it to continue to cool after the enging is shut off and operates much longer in hot weather than in cold weather. If you think it is cooling to long before shutting off I would check the cooling system to see that it is operating correctly. If no and the engine is overheating somewhat that is why the fan runs longer.
Is the heater nice and hot when the needle shows low temp? If the cooling fans turn on and the heater is hot, that leads me to believe the coolant temperature sensor is bad. You should try replacing that sensor. They are only $6 usd here. As long as your check engine light is not on and your fans are running, this will not hurt your car... but this is something you should fix soon if you can. Make sure the engine is cold when you replace the sensor
It would be normal for the cooling fans to run after you shut the car off because the power to the fans is turned on and off by a thermostat and not the key. Don't worry about it unless it runs for more than 15-20 minutes when you shut the car off. It may run that long in summer if the car is hot but less in the winter. Hope this helps.
the computer is reset when the battery is disconnected, it takes a few days to relearn your driving habits for idle strategy only, it would have not affect on the cooling system of any kind. check and verify the engine cooling fan is running, if u have AC turn it on, this will cool the engine down and should engage the fan. Make sure that no connectorsnear the battery were left unplugged or accidentally unplugged.
There is a relay located near the top or side of rad saddle or fan shroud, trace the wiring harness from the fans to this relay sounds like the relay is fused together or shorted out, or as simple as checking your temperature control setting inside, if you have a/c and have the fan set to any position other than off, and the hot/cold dial is in the blue those fans will always be running when engine is. Easy to check this, just have the car running and turn off your fan or turn your temp selector to max hot. If the fan still runs even when the engine is cold then revert to my first check on the fan relay.
there is a cap on front low on trans but you have to pull drain plug don worry nothing will come out unless trans is already full if it needs fluid none will come out i am a vw tech and i know that sounds off the wall but it is true
