Engine oil measurement not functioning
Any idea why the oil measuring won't work?
The oil was at the right temperature, the car was level and tried several times but with no success. The measuring process starts but it goes off before reaching 20% with no explanation/ message. Let me know if you have any clue The engine revs up 600 RPMS from 700 to 1300 immediately after it starts measuring. Measuring stops at about 17% and then the revs return to a 700 normal.

I will post my findings so far, but this seems to be happening more often than not to some BMWs.
I have never had an issue with the sensor in my other BMWs, but a couple days ago at the gas station, when I normally check my oil level, I had the progress quit at 22% and no other errors would show. I tried three times and it would fail at the same spot. I turned off the car pumped my fuel and when I got back in the car, I tried again. It worked! So I moved the car and went to another level surface to try again. This time it would fail at 38% consistently after three tries. I decided to research and this forum came up empty. I saw a YouTuber with another BMW (F34) where he has the same issues and he then cleared the error in the memory. I tried that and went for a driver, checked the oil once and it worked, but I have not checked it since to see if the fix is clearing the codes. The bahaviour seems software related. I will keep and eye and report back any changes or even fixes if it continues to do it. Update: I have read the oil level a few times since without issues. Seems to be a software issue on my part. Still want to know what OP’s fix was/is. |

BMW techs at it again……… Man these guys cannot diagnose anything. Why was the conclusion to change the oil pump?

It is probably easier for the less trained mechanics to replace the entire oil pump unit than to diagnose, open it, replace whatever and restore vehicle's functionality and safety. Last edited by STEALERHSIPS GONE SOON; 02-05-2023 at 09:38 PM.. |

Did the car have low oil pressure? What did BMWUS actually said as to why the oil pump needs replacing if the oil sensor is not working. Changing an oil pump in a B58 is no easy feat. The transmission has to come out say the least. I want to know more because this does not seem to be just an oil measuring sensor issues. Break break. And for those here. I have measured the oil several times without issues after the software error clearing. My engine also maintains good oils pressure the times I have checks. |

BMW US does not talk to customers about the failures of their vehicles, therefore the difficulty in knowing what they said on this subject. |

The engine oil must be fully warmed up before the noise occurs. It was a whining/whirring noise that changed pitch with the engine RPMs. It’s most noticeable with RPMs between 1500-2000. It was easy to hear in stop and go traffic. At higher speeds it’s difficult to hear because of road noise.

The car is whisper quiet inside with the windows up. Also I noticed that mine measures the oil just fine; however, it does not like to do it after short drives (it stops at 21% every time) after the car is restarted, it will measure it just fine. |

I can see whining noise associated with RMP could be oil pump, because it is driven by crank, but it is also possible for other component driven by serpentine belt, right??
Not that I don't believe you, but oil pump failure is very uncommon. It is entirely mechanical. if it is faulty, the only observation is oil pressure inconsistent and/or low. There isn't a code directly point to oil pump. And I don't see how this can impact oil level measurement either.
