i changed my oil 5/10 16k miles and reset the idrive. i checked it today and it says "ok" and i have 7000ml and with a 6/12 due date...wtf. the car has 27k on it now and it hasn't been for any service and i didn't touch it "service wise" since last year. What gives??? is idrive that big of an idiot since oil service is 1 yr or 10k depending on how you drive. why would it just reset itself?
