2007 525 Touring. The temperature gauge fluctuates dramatically

Customer Question

2007 525 Touring. The temperature gauge fluctuates dramatically , particularly at higher speeds. It rises to 16 degrees C and then drops to -40c - the ice warning icon comes up. I am assuming the sensor or thermostat are dodgy with possibly an open connection that picks up air, and as I drive faster it becomes exposed to the wind??? Is there a quick check or fix - not sure where to look for the sensor.
