My engine mangement light keeps going on and off randomly but the engine does not run differently with it on or off. On my mates code reader it showed up as an Engine Coolant Sensor fault and we reset it, topped up the antifreeze. As I looked to see where the sensor is positioned and there's a plug for the sensor on top of the coolant resevoir but no sensor plugged in or near by, Does anyone with a 1.2 have a sensor here?
