Exactly what is the light doing? Steady on, blinking slow, blinking fast?

3. Engine coolant temperature too high
light is lit; pointer on the right
4. Temperature sensor at water outlet faulty
light flashes rapidly (1 Hz); pointer on the right

The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously
(1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash)
