That's how the gauge is designed.
Possibly so the driver will suddenly notice it.
Pants design if you ask me :xmas-smiley-024:
On my diesel this wasn't quite the same.

I had an airlock causing my diesel to overheat a mile from work. I noticed as the heater was freezing cold, so activated the ipk display. At 105° the needle went to roughly 47 mins past (ie just over 9 'o' clock) then went to about 8 mins to 12 just as I arrived at work when the display read 120°. My fan is obviously kaput but it didn't illuminate the warning light. Air lock now sorted and now saving for a new fan.
