Thread: Any thoughts on a TD5 temp gauge UNDER reading....

I have now noticed that the electric fan on the front of the radiator stays on. Not all the time, just when the engine is running.... I don't know what this fan is for, as it is not on the RAVE CD. The only reference I can find, is that it might be for the AC and goes on at 28 degrees and goes off again at 25 degrees (outside temp).......

Any ideas of how to check why it is being switched on?

I am going to disconnect the battery for 10 mins or so, to reset all the mem's etc....

Let you know if it helps.

Seems like there's a temp sender wire that's loose and the ecu has gone into protective mode and runs the fan all the time. There will be a fault code for the temp sender that has to be cleared and then the fan will stop running.

Agreed
