To clarify... Oil level sensor.

Well, from my understanding low oil pressure can indicate several things, among others one of them being low oil level.

Some possible problems could be as simple as an electrical connection, bad sensors, wrong oil to a more costly DME replacement (yikes). Maybe he needs the software cleared/reset? I don't know. I'm no expert on the software DME so I won't surmise past that, but by me suggesting "maybe it's a bad pressure switch" that far fetched and/or incomprehensible? Will it hurt to try replacing a cheap part/sensor (that is old) known to leak in the V8's and just "maybe" solve OP problem? If it helps, GREAT! If not then some will continue to help and contribute...

A faulty pressure switch will not give a low oil LEVEL. A leaking pressure switch might cause the oil level to be low, but then the leak would be obvious, which does not seem to be the case here. A leaking oil pressure switch is not considered a faulty switch, so changing it if there is no leak and no low PRESSURE indication is worthless and unnecessary.

Their seemed to be some confusion in whether we were talking about a level sensor or a pressure sensor, since there was interchangeability of the terms. I was not trying to diss you.

We both understand what an oil pressure sensor does however, figuring how the algorithms in the DME sort out defaulted sensor readings is beyond me. As we all know and are familiar with, the error readings we see for the most part are cut and dry. Obvious fixes, just replace the defective part and you're all good. But sometimes things such as this happen (fairly often I might add). The "obvious" issue here was the oil level sensor. OK no problem. Replace with new one and be done with it. Unfortunately this didn't help him. So there's something else going on. Others chimed in to check connection and so forth (which is what I'd do). Hence, I just thought the next logical thing to do would be to check the pressure sensor because frankly we have no idea what signals the DME is receiving to still show low oil level when in fact the level is fine. Somethings amiss. You may not agree but that's fine. Just trying to explain myself. We all have our opinions and this is what makes forums what they are, a diverse community with a whole lot of knowledge.

Thank you all for your input! Come hell or high water... we'll figure it out!

Hey guys.. any updates? I've got an 07 525i and my oil level sensor is reading min oil.. I replaced the sensor and still the same reading.

Hello all.
I got the same error with oil level too low and comes when i drive semi fast at highway (150-160 km/h) after 20 min. My BMW E61 530d 2006 has a deapstick so i checked oil level - at max.
Does someone have a solution to that?

any updates? have an 08 520i 6mt with the n43 engine, getting oil pressure too low when driving aggressively 170-200, the car doesn't make any strange noises or rattling, i stop the car restart it and the message is gone. car is gone 240k autobahn kms, but is in mint condition and hasn't been beaten on. any ideas on what it might be?

Resurrecting an old thread as there's no sense in starting a new thread and getting the "why didn't you search" responses....

So I have a 2007 530xiT with around 187,000 miles. In the past eight months or so I've replaced the oil sensor twice, each time with a new unit each time from FCP Euro. When I got the car back in November 2019 with 177,xxx miles all was fine. Then about 8 - 12 months ago I started getting erratic oil level messages. I could go from middle to full to "add a quart" in one 30 minute drive. First replaced it in December 2021; still got erratic messages. Replaced again a few weeks ago; still getting erratic messages. I assume nobody's found an actual fix for this...?
