I don't know about the IAT? Why did you replace the intake air temperature sensor? Also why was the thermostat replaced? Was there a trouble code stored PO128? If you did and thermostat is ok and engine coolant temperature sensoris ok then you would need to take it in to Volvo to have the engine control module reprogrammed with an upgraded software if it is available. The reprogram is pretty long and the longest I have seen it take is about 4 hours to do.
