It's presumably got an electronic oil level gauge - such a message probably means that an error in the sensor or circuitry has been detected - you'll need to get the diagnostic codes read, cheaper from a good local independent than a Peugeot dealer.

Put "Peuegot Planet Map" into Google, it tells you of local Peugeot and Citroen owners with Peugeot specific diagnostic software.
