Ah ok , check at the back mate even number plate lights they usually give trouble if warning is on and off , give them a few little taps with your hand see if they go out or in fact come back on ,👍

I had the same thing, it was one of the reg plate lights mate, eventually the bulb blew, I think they can be dodgy for keeping a good connection to the festoon bulbs. I swapped mine for LED and just bent the contacts inwards slightly. No problems since. I think the system checks for bulb out by measuring resistance on each lighting circuit. So there is no sensor as such, just the bcm or ecu (someone will be able to correct me) that looks for a set value, I don't think it knows if its open or short, it just knows the value isn't right so throws up the dash warning.
