If you have the old-type coolant level controller (1.9l and earlier unless
replaced) there is absolutely no way to distinguish low coolant from
overheating, because what the controller does is simulate an overheated
gauge sender.

If you have the new controller, it does the same -- except that it only
does it in short pulses, sufficient to trigger the blinking light but not
long enough to move the gauge needle appreciably.

I'm surprised that GW wouldn't have found a way to trap that later
behavior.  The gauge blinker itself does it with few components.

Yrs,
