Engine oil pressure low flashes on then off

Hi all. When I turn my 2013 Bmax on, it flashes the engine oil pressure low on the screen and then disappears. It happens every time I turn the car on. Is it just a faulty sensor or something? Shouldn't the light stay on if the oil pressure was actually low?

note most oil filters have an anti drain 'valve' (actually just a flap of rubber over the feed holes) and these can fail
also if it is a turbo engine; do it much sooner than later
other engines should be a little more forgiving

Hi all. I've checked the dipstick. There is oil. I got the car in March.

Have you checked to see if the "fault" is actually the car testing the circuit to make sure all is well ?
It could be the sensor being given a signal and the signal being sent back to cofirm it is working correctly.
Ask a local dealer or independant garage if they can shed some light on it for you.
As long as the message does not stay on, and the car drives ok, then i would say you have little to worry about.

But it's strange. If it's testing it, it should to it in the background. It shouldn't just come on and alert me oil pressure is low and then disappear. I'll ask the garage. Thanks.
