Hi and thanks for your detailed analysis. But just to say again, that it never was overfilled in June 2016. For 8 months, there was no overfill, and has not been triggered until the past 6-8 weeks. How could it be overfilled then and not trigger a warning for 8 months (if it is that sensitive of a system), and now trigger an overfill if it is that sensitive of a system? Then it wasn't functioning properly before if it was overfilled, and gave a false negative reading for 3/4 of one year. Isn't that right?
I did the oil change myself, been doing it for years on all vehicles. As is always done by me, the oil is underfilled a bit, confirmed by the multiple assessments on the sensor (which I know is not perfect), then properly added in small increments to bring the measurement up to the proper fill level. It was changed 8 months ago--and did not show these errors anywhere in an 8 month period, so I don't think the expansion suggestion makes sense in this case. It should be happening ever since the change, rather than only recently.
Curious if anyone here has any info or history with an intermittent warning message for oil being OVERFILLED. 2015 Cayenne S, 15K miles. Oil was last changed June 2016 and meticulously brought up to the proper level over a short period of time. Volume matched proper fill amounts as well, so no mistake on the amount added. Never had any such messages until about now 2 months ago. Intermittently will come on, stay illuminated perhaps for 1-2 drives, each in excess of 30 miles or more. Then just as started, goes away without warning. Absolutely no control or dynamic changes on vehicle, except for 2 rare items, also perhaps over same interval of time. On rare occasion at a stop an irregular at idle under proper RPM, but no driving impairments. Also on maybe 2-3 separate occasions, a backfiring sound with ignition (not hot or cold isolated), but no warning messages alerting with it--and none is consistent with oil overfill warning as well. Just 3 separate diagnostic issues that don't always correlate with one another--but have evolved in this broad time frame of 2 months. Called one service place--to ask about setting up appt--was told it's from not driving the car long enough, and was told oil must be sloshing and dripping on areas that trigger the sensor. I call BS on that--I'm not a soccer mom (nothing against it) driving the vehicle and enjoy DIY'ing the vehicle etc., and am very clued into the systems of it all. Didn't even want to really have me come in. Are you kidding me? Moreover, after an additional 8000 miles since the proper oil fill, it is impossible there is more volume in that pan than 8 months ago. Arguably a decent amount below the max fill given my enjoyment of utilizing the vehicle to full dynamic ability often when properly warmed up. Oil should be being consumed in other words... The service mgr told me it is a sensitive system and if filled nearly to the top it can do this. Does anyone know the failure mode of this alert exactly if it's not truly high? Can anyone put together the other aspects (btw, which haven't really persisted but the oil alert is occurring nearly ever 3-4 drives now?
OK, thanks, actually someone else recommended a jump between it to prevent it in general, of course deactivating the system entirely, which some may find a safety issue with it not in neutral, but aside from that, what is the procedure to do this and how to if so?
I am planning to replace the defective aspects of this system because of recent error messages I am starting to get. I see there are two parts possible to use: 1.) a clutch pedal switch (red), and 2.) a clutch pedal ignition lock switch (white). Must I replace always both, or is one usually the culprit in this failure mode? Thanks
Greetings. I have been trying to find a nice diy thread with photos showing the appropriate panels to remove, the respective locations to drain, etc. I have looked and found something relatively old with the earlier generation models, but don't see anything else. I have happily used the ones in the past with regard to the 911 as posted on Rennlist and elsewhere. Has someone here put together a nice photo step by step, just so I can see it correctly the first time? Many thanks.
