I agree with Sid.

If the level is fine then either the oil pressure is really low, or the oil pressure switch is faulty.

The main dealer should be able to narrow it down. They can connect a proper oil pressure measuring gauge to determine which of the above it is.

It's probably the sensor which is easy to replace and reasonably cheap.

Also check the electrical connection to the switch. It might be corroded up.
