Oil level not reading

[markslc1]

14 x35i. Just changed oil and I drive is giving the message. "Oil level measurement inactive"

I'm guessing a sensor has gone bad since no amount of warm up or driving makes it work again. I also cleared my codes. Ideas welcome

[RED_Y_]

How did you clear codes?Which codes are they?

[XxBBVTMxX]

The sensor is #6, check the area on your oil pan to make sure the cable connection is ok. If not, the part # is 12618608780. Get some oil and filter if you decide to change it because you'll have to drain the oil (or you don't have to &#128517. FCP Euro and eBay has some. Hope you get it fixed

Good advice. I'll check into it.

Here are the codes

It appears my oil temp sensor is not reading. Is that the same as oil level sensor?

I took a look and all the electrical looked good from underneath. I hope a new sensor fixes the issue because they are not cheap.

Still open to other troubleshooting ideas.

How many wires going to sensor? It may be combined if there's more than 2 wires.
And can't see your pics.

It's a single sensor that does both level and temp. Single plug

I replaced the sensor today. No change! Still can't read oil level. So I guess it's software? Maybe something needs to be reset?

Just to verify...reading through this thread I see no mention that you met all the criteria for running the oil level check. Have you met the criteria? The oil has to be at operating temperatures. If you changed the oil...the new oil is cold/cool...and not up to operating temps...so you would need to run the engine until it reaches the temperature criteria for the level to be read.

Good point. But yes I make sure the car is good and warm. And attempt to measure on flat ground. No matter what I do the system still says the oil level cannot be checked. Nor can I reset the oil service interval.

Which method are you using for oil service interval reset? Are you using a tool...or are you attempting the instrument cluster button reset procedure?

If using the instrument cluster button...if you haven't reached a specific criteria...you can't reset the service light. For example, right after resetting the oil service inspection light...you can't reset it until a specific amount of fuel (or is it miles) have been used (see pic below of my 6 series instrument cluster where it says reset is impossible). I had just changed the oil and reset the cluster in April/2021...so the next inspection isn't due until April/2022. At the time of the pic...I had driven enough miles to do an oil service reset...thus the cluster says "reset impossible".

My X5, though...the oil service wasn't due until June/2021...and at the time of the pic it was May/2021...thus it was possible to reset the X5's oil service.

When attempting to reset via cluster I get "reset unavailable" message. And still no oil level reading. If not the sensor and wiring looks fine I'm not sure what the next step is for troubleshooting.

Is there a reset procedure?

Have you tried reading the codes? If the car knows to report "rest unavailable" it should be getting a signal or lack thereof and throw a code. That might help further where to look next.

I thought I would update the thread with the solution my mechanic discovered. Turns out the n55 has a second oil temp sensor in the block under the intake manifold. Rodents had chewed the wires which caused the oil readings to malfunction. Some soldering and labor and I'm back in business! Wish I didn't spend the money on replacing the oil sensor in the pan. But live and learn.
