thermostat issues?

Hi

Has anyone had problems with the thermostat showing red light Even though there is enough cooling water?

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

Note
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)

You might have better luck posting in the proper forum category.

This is the Boxster and Cayman Detailing Discussion forum. Try the "General Discussions" forum.

Sometimes the simplest thing is the answer. Make sure your coolant cap is not cross threaded and make sure you have the latest one ending with 04 in the part number.
