Because the thermostat was in the open position it allowed the engine to over cool (blue light)
By doing this the ecu produced a richer fuel mixture and lower mpg
Once the thermostat was changed the blu light stayed off. The mpg increased and the heater was a lot warmer in the car
Hope this helps

took the thermostat out and it wasn't closing when testing allowing to cooling system to over cool
changed the thermostat and has stopped the blue light coming
the blue coolant light sometimes goes on and off after a run even though the engine is hot
I thinking that this could either be a faulty switch or wiring issue
Anyone else had the same issue and know the cause

I can't see where it would plug into given the range it could fit
The other...
