I've been getting some inconsistent readings from my oil level sensor over the past few days which have me a bit concerned.

Prior to taking the car away on a trip for the weekend it was reading at one notch below maximum (250ml below full), so I added a quarter of a litre to bring it up to max.

After driving the car, the level didn't go to max, but instead dropped to the half way mark (500ml below full). I chalked this up to the classic weirdness from these sensors and kept driving. Despite me forcing many re-checks with the BC button, the level remained at the half way mark all weekend until Sunday afternoon while I was driving home, when it began reading at the full level again.

Great I thought - the sensor has finally re-calibrated itself and now it's reading correctly.

Sadly, this was short lived, as the sensor has since gone back to reading at the half way mark.


I am pretty accustomed to the way these sensors behave as I also have an E63 M6, so I know their quirky behaviour, however this seems a bit more unusual than anything I've seen before.

The car has no codes and upon running a check on the sensor in ISTA the software says the sensor is ok and it reads out the oil level in mm with no issues.

Should I replace the sensor as a precaution (at BMW's outrageous price) or give it some time and see if it stabilises?
