Golf 5 2.0 litre fans starts up even on cold start,keeps on running until ignition is turned off

Unless you have a complete electrical problem, the only time the fan should come on at start up is if the AC is on.

Hello Olivier, I am curiously if you solved the problem with fans which start up after the engine start. I have the same problem and I have no idea what could be wrong.

Has anyone solved this as I'm thinking to believe it can be the relay switch as when I knocked my fan it shuts off

Hello Craig, I changed both fans, temperature sensors, from alternator I changed the diode bridge and the relay an I have the same problem. In my case the command for fans to run is received from injection (engine) ECU.

Hi there; am having a problem with my golf5 2l the fan comes on immediately after starting the car n with alot of noise then when i try to accelerate its not moving while the fan is on with alot of noise. Pls help

I wanted to find out that how was that problem solved ,cos im facing the same problem and my car dont have a cooling fan control module.

I have the same problem did you solved your problem and how

I have the very same problem...any 1 who can help

In my case the car idles low when the fan runs, and my temperature gauge is not working. Can it be possible that the temperature sensor is sending the wrong signal to the ECU thus causing the radiator fan to run because the ECU thinks the engine is running hot?

has anyone solved this issue
