Tejas1836 wroteWhen it happened to me, I did not know if the oil was OK. I assumed it was. When it finally read it, the oil is almost at max.On the vehicle status screen, when this happens, is the oil level status "OK"?

remeeno wroteBMW techs at it again……… Man these guys cannot diagnose anything. Why was the conclusion to change the oil pump?I had the vehicle diagnosed by 3 different BMW shops.
They all gave the the same (re)solution - the oil pump replacement - which I finally had to do after all.

remeeno wroteBut the oil pump has no bearing on the oil sensor measuring. Oil pump just moves oil around and maintains oil pressure in the system.Because that is what BMW USA told them when they opened the TSARA case
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.
AGONXF30 wroteBMW US does not talk to customers about the failures of their vehicles, therefore the difficulty in knowing what they said on this subject.But the oil pump has no bearing on the oil sensor measuring. Oil pump just moves oil around and maintains oil pressure in the system.
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.
AGONXF30 wroteB58 oil level measurement problems are almost always due to the oil pump. Many have reported the dealer replaces the sensor and it still doesn’t work. After replacing the pump, problem solved. I have a 2020 M340i and was unable to perform an oil level measurement and also had a very audible whining noise coming from the engine that followed the engine RPMs. Faulty oil pump was the issue. Low oil pressure according to the technician at the dealer. After replacement, no more noise and I can measure the oil level. FWIW, no transmission drop required in the M340i but still a very pricey repair if not done under warranty.But the oil pump has no bearing on the oil sensor measuring.

CrownRoyal79 wroteDid the dealer clear any error codes before charging the sensor? Did the sensor change not work? What is the PSIG of the B58? Same as the N55 or similar? I have issues with the measuring, but only after the HU gets some error and when I clear then, the measuring is fine for months.B58 oil level measurement problems are almost always due to the oil pump.

AGONXF30 wroteNo error codes at all. In my case, they didn’t bother with the sensor and went straight to the pump due to the whining noise.Did the dealer clear any error codes before charging the sensor? Did the sensor change not work?

AGONXF30 wroteThe 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.What was the noise like and when was it present?

AGONXF30 wroteNo, with windows up it’s easier to hear. If you can hear your engine rev with windows up then you would be able to hear the oil pump if it was whining.Windows down I presume!? I have the acoustic windows and I can’t hear anything mechanical inside the car.
CrownRoyal79 wroteWith the acoustic windows you cannot hear anything inside the cabin related to the engine. So I guess you do not have acoustic windows.No, with windows up it’s easier to hear.

eelnoraa wroteB58 oil pump failure is actually pretty common, midway through 2020 they changed the oil pump as the old one used plastic. Why bmw would put plastic in an oil pump is beyond me....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.
