I’ve noticed it is when it does a longer countdown it says all is well, if that means anything. My drive at home is an incline, which people inside the Internet seem to think makes a difference.Sundayjumper wrote: ↑Sun Aug 18, 2019 8:45 pm The one in my 996 will depend on the conditions - based on the temperature and how recently the car ran the dash gives a countdown of how long you need to wait.
Fully warmed up then left overnight so it’s stone cold should = most accurate reading.
Still warm and/or only started briefly then the oil hasn’t had time to drain down completely.
It may well be easiest just to add a small top up and see what it says after, although I worry about over-filling.
