Normally my beep comes at around 7-7.5 almost 8 k/revs. But just now it came in at somepoint between 6 and 7 :/ any ideas? Happened twice. My service is due and the light is on? Could it be that?
It's more the oil temp than the water temp; don't forget oil takes longer to heat than water. The ECU works on oil temp and changes the limiter accordingly I believe.
