What makes the light come on as there is no oil deficiency?

Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you

this is the oil pressure light, not the oil level light.
this light comes on when oil pressure as measured by the oil pressure sensor, drops below a minimum threshold

the light commonly will come on if the pressure sensor is faulty, or if oil pressure is in fact low for some reason (ie: failing oil pump, internal engine wear)

as a next step, I would replace the pressure sensor and have the pressure measured manually using an external guage.

if you need a good non dealer option to cut down on costs, check out www.bimmershops.com or www.bimrs.org for options.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
