Just changed the oil in our 08 X3 (in between service). I noted that when I checked the oil level, small 'clock' shows up while calculating. I cannot remember seeing that before. Best I can find on the forums is that means the stored value for the old oil level was cleared and a new one is being calculated. I couldn't find anything in the owner's manual on this. Is that correct or does anybody have the real story? thanks in advance.
