Hello, please help me solve the problem with the engine fan running. After overnight parking, the engine is cold, the battery is disconnected, I connect the clamp and after 10 seconds. the fan on the radiator starts working, the key in the ignition is turned to ignition, the fan slows down after...

The controller comes with two thick wires and two thin ones. Thick is power, thin is a plus after the ignition switch and fan speed control, probably a green wire. Unclip the thin ones and how it goes without them is a problem in the fan.

So it looks like the fan is broken. Too much consumption. It should be about 20mA or 0.02A Unless you ask about the fan current it can be.

The easiest way would be to connect with something and check for any errors. Maybe the temperature sensor is broken and gives information that the temperature is too high or out of range.

It is rather not a sensor, since the fan works after switching off the ignition, the controller is in the fan motor.

In 2010, Superb II came out with the 1.9 tdi engine ????

I gave the power to the windmill for those thick for a short time and the windmill is working. Added after 2 [minutes]: One more question, can the current consumption of the battery be 1.85 A, that's what I measured? Added after 1 [hours] 36 [minutes]: Pictures of this fan

Unclipped fan and such current measured in series by the clamp.

It's the only thing that makes me wonder why you disconnected this clamp The rest is pikuś, the fan turned on, and the electronics are awake.

Hello col. Strumien wrote why you disconnected the clamp

The fan is 100% damaged, I disconnected so as not to discharge the battery.

Hello, please help me solve the problem with the engine fan running.
After overnight parking, the engine is cold, the battery is disconnected, I connect the clamp and after 10 seconds. the fan on the radiator starts working, the key in the ignition is turned to ignition, the fan slows down after starting the engine, the fan stops working. After switching off the engine and after 10 seconds the fan starts working again. There are no errors when connected to the computer.

The fan is repaired, the module on the fan is damaged, but there is a problem with the leakage of electricity.

Topic summary

The discussion revolves around a 2010 Skoda Superb II with a 1.9 TDI engine experiencing an issue where the radiator fan operates continuously after the engine is turned off. The user reports that the fan activates shortly after reconnecting the battery, slows down when the engine starts, but resumes operation after the engine is switched off. Despite no error codes being detected via diagnostic tools, various suggestions are made regarding potential causes. Responses indicate that the issue may stem from a faulty fan control module rather than a temperature sensor, with recommendations to check the wiring and current consumption of the fan. The user confirms that the fan is damaged and mentions a problem with electrical leakage. The discussion concludes with a note that the fan module is defective, leading to the fan's continuous operation.
