engine cooling fan should not do this - bad temp sensor likely
the normal running engine temperature on the passat is 195 degrees , most of the time the primary cooling fan gives out and they run somewhat warmer than that.a belt connects the primary and secondary cooling fans ! you may check the belt if your passat is running warm.

one fan is your normal cooling fan the other is for when your a/c is on to check if it is working simply turn your a/c on and both fans should run at same time
Engine overheating or cooling fan running all the time.
Sounds like the thermal switch needs replacing.
2001 VW jetta the radiator cooling fans run all the time they run soon you turn the ignition switch on with cold engine. if the engine is hot and you turn the ignition switch off the stay on till battery goes dead.
I can't speak for that SPECIFIC car and model but on most cars with two fans, one is driven by the engine belt and runs whenever the engine is running. The other runs electrically and can turn on (usually) if the key is in the ignition. There is a relay and a controller that tells that fun if the engine needs cooling. On some cars this fan will run even if the key is not in the ignition; i.e. parked and the driver away from the vehicle. It should stop when the sensor running it decides the engine is cool enough. Both fans are electrically driven and have two speeds. The fans operate at a lower speed until a certain temperature is reached, at which time they both switch to high speed. The two fans are always on the same setting: Off, Low or High.
On a 10 year old car it is time for a complete cooling system service. Drain and flush, replace the thermostat, inspect and replace as necessary all hoses. Also replace the thermal switch for the cooling fans.
I've seen this happen in Honda's. Does it remain running for long periods of time or never shut off? If it is only running for a short time, it's cooling off your engine still because it's still really hot. There's nothing wrong with this.
Why does the temperature gauge on your 2001 malibu not work and the cooling fans run all the time?
If cooling fans stop working and engine runs hot wtih A/C on usually excessive head pressure will build in a/c compressor and refrigerant will discharge from system. cooling fans may have a bad fuse or relay should be repaired prior to recharging a/c
The cooling fans will run when there is a signal calling for them to come on. High temps will do that. Also anytime the ac is on, a fan will run. Try turning the ac off and see if one of the fans stop. Do this when the engine is cold. If the fans run anyway, check your fan relays, they may be stuck on.
