I changed the oil in my E70 4.8 this weekend and now I'm getting an oil level sensor malfunction. I have checked the oil with the dipstick and it is fine. When I go to the screen I have all green indicators but when I turn off the car I get the notice that the oil level sensor has malfunctioned. I can clear this out and then the next time I turn the car off it reappears. Has anyone else had this issue?

I've been changing my own oil for over 30 years and never had any issues. Why would this sensor start showing a fault after an oil change.

Thanks for any help,

Mike
