what year is your car, because early cars have what we would call proper oil pressure switches and read actual oil pressure, later ones don't.

as for why, it might be a faulty oil pressure switch, have you checked the oil level?

If it's the early type then it could be the sender unit - they go faulty after a bit and they aren't cheap to replace.

It's a late 16v... I've just literally done a full service on it so I'll see how it goes

I’d say it is probably the sensor that is failing.
