Display says low on oil, dipstick shows normal level ??

[NorwegianRT]

That oil light is for low oil PRESSURE, not low oil LEVEL. Should go out with engine running. Normally on with engine stopped. If it remains on with engine running, it’s a problem. Troubleshoot if valid low pressure, such as filter, sender, harness, and could actually be a pump or gear failure.

Hi Doug and thank you for info!

Feeling a bit stupid here
Of course it is the pressure and not level. I got the same thing in my boat and car, shuts off when pressure is up!
I will have a look at things when doing oil and filter change soon!
