I have a 406 HDI 2.2, (02 reg.) which I have had six months. Total mileage 44K.
While driving, the STOP light started to flash and window warned that 'Engine temperature was too high'.
I noticed that the temperature gauge was at zero and having stopped, found that the radiator fans were on full blast. As I had only left home five minutes before the radiator was barely warm so obviously an electronic gremlin!
Any ideas? I wondered if the temp sensor had failed but could not find it to test. I noticed that when the engine was switched off, one of the fans continued to run for several minutes, presumably timed.
dylann is desperate!
Instrument Fault with STOP warning

The radiator may have been cool, but what about the engine? If your coolant's not flowing properly (low coolant, broken water pump, jammed valve on the radiator circuit?) your engine could be melting because no coolant's getting to the radiator to cool down.
Alternatively it would make sense for the ECU to assume the worst if it can't read the temperature...

<steve_earwig> I think this forum is more about keeping our cars going with minimal outlay than giving our cars more reason to go bang
The warning was definitely false; both engine and radiator were merely warm.I found what I believe is the coolant sensor on the cylinder head (front, middle) and disconnected the three wire connector. No effect. Next to it is another two wire connctor. Disconnected this and 'STOP' light out went out and no fans or warning. What is this connector. or have I just fooled the ECU by disconnecting it.
