Do you drive mostly short trips? How many quarts did you put when oil was changed? Each segment is approx 0.45-qt, therefore, if your oil level showed full (just the top 'overfilled' segment not lit), that means that you could have, in theory, 0.01-qt or 0.45-qt in that segment. My guess is you were pretty close to full, meaning near 0.45-qt on that segment. If you only use your car on short trips, the condensation accumulation on your oil would rise its level, triggering an overfilled warning. You definitely DO NOT have an overfilled sump because you've been driving like that for months. It's either what I'm saying, or an oil sensor issue, which I doubt since you've done nothing to your car since the oil change. My suggestion is to first open the hatch, to clear the present reading. Then go for a long ride, of at least 20 miles (I'd do 25). Then park in your level garage with the engine idling, open the hatch again, close it, grab a watch with a second hand (your chrono -if equipped- would be perfect), make sure TFT is in the oil and coolant temp mode, shut the engine off, wait exactly ONE MINUTE, then turn ignition on, push TFT lever forward to get into car settings, choose oil measurement, and push forward again. That should give you the true reading of your oil level. Report back and we go from there. Good luck.
