So I just had my Oil changed at my Indy and even though they believed they had reset my interval notification, I just noticed that when I go into iDrive and Service Menu, it shows "Unable to determine Oil Level"
However, the "ALL SYSTEMS OK" also shows.
So when I access the 'Odometer hidden menu' that allows you to manually reset the Oil, Brake, and Service Reset, it show: "Reset of Engine Oil Reset Impossible"
Any ideas...
