Default Oil Overfill warning on new Panamera 4

Last night, on the way home, I got a warning light saying that the oil was overfilled. It went on to say that I could drive the car, but that I should take it in for Service. The car is about 5 weeks old, has 1300 miles on it. I didnít make too much of it but it was still on the next day. I called the dealer to arrange to bring it in. Of course, after the appointment was made, the light went out! I took it up to the dealer, they checked the oil level manually, felt there was in fact too much oil, and they took out a little less than a quart. The oil level is now about 3/4 full. The service rep says that they fill it to the top at the factory, but then after driving, the oil volume can expand and tip the sensor. No harm, no foul. Car is otherwise faultless, doing very well in the bitter cold and snow with a set of Continental snow tires. Let me know if any of you have had this problem....drive safely.

I think just about everyone who drives a recent model Porsche has had this problem at one time or another. The electronic oil level monitor in their cars is, frankly, crap. When oil reads low, it takes only a very small amount to fill and then overfill the tank. If your oil level sensor reads at the very bottom of the scale, 1/2 quart will overfill the engine and fire up the warning lights. You practically have to add oil a tablespoon at a time!

And there are more problems with the system than just that. In my GT3, if you open the trunk lid (to, you know, add oil) it won't permit you to read the oil level immediately. It takes its time, and by that I mean it can be days or even (this really did happen to me) weeks before it will give you a reading. Also, it's very sensitive to oil temp and won't give you a reading if the temp is too high or too low. So, for example, when I come in from a half-hour track session, I cannot check my oil level until it cools down. WTF? This is the time when I MOST need to be able to check it! After that, if I do manage to check it successfully and add oil, I won't be able to check the level again that day. Again I say -- WTF?

I've complained about their oil level sensor on every Porsche survey I've received over the last several years. I've had two Panameras and 5 911s in the last decade, and everyone of them had the same stupid system. My dealer says "we hate it too, we'd rather have dipsticks too, but Porsche thinks nobody will ever check them so they need to do this."

And you can see how much of an impact I've had on them! The stupid oil level sensing system, the stupid cupholders in the 911s and Boxster/Caymans - remain unchanged.

How can a company that does so many things so well persist with this crap? AARGH.

My 2010 4S presents no problems maintaining the oil level, my garage fills to the 3/4 mark and when the level drops to 1/2 I can add a half quart and restore the sensor back to 3/4. With nearly 60,000 miles this has been consistent although I will say that I'd prefer a dipstick for immediate filling feedback.

I have just got this message today on a Panamera 4 E-Hybrid. Just a couple of months old and only done 750 miles. Irritating as I have never added any oil, so how can the oil level be high unless it has blown a head gasket and is leaking coolant into the sump. There is no audible indication of a blown head gasket and no excess steam in the exhaust.
