Check oil level warning

Matt

Hi i drive a Bertone and get a Check Oil Level warning on the computer. This usually appears after 10-15 minutes driving and isn't there immediately after turning on the engine. Iv checked the oil and the level is fine. Anyone know why this is happening?

Cheers

possibly the oil pressure switch?

How many litres do you fill up with?
Are you checking with engine warm or cold?

Hi i only checked the oil level with the engine warm but now im noticing the trip computer immediately saying check wash fluid and then check brake fluid and then check oil level, possibly the computer is nackerd? ps the oil was changed only about 2000 miles ago.
