Engine fan is constantly on. Help please!
There seems to be an issue with my Audi (A4 Avant Sport 1.9 TDI 130 2002) whereby the engine fan is ALWAYS on. Even when I first start the car in the morning the fan comes on immediately. Also, if I turn the key to the on position without starting the engine the fan also starts and stays on throughout the journey until I literally switch off the ignition. The temp gauge is working fine. I'm guessing there's a sensor or something that is giving incorrect feedback regarding engine temperature. Any ideas what might be wrong? I hope I have explained this alright!
Thanks in advance for any assistance/ideas :-)
