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 :-)
