I feel you.. I asked my SA why they don’t replace the oil sensor and he said he need to get approval by BMW.

G20 FB group ppl who got the same issue, they normally solved it by replacing the oil pump.

Now I doubt they really did replace the oil pump.

Tells me that maybe something is wrong internally with the engine and it’s unable to keep oil pressure within the specified parameters. Ive found the cut off is 47psi, any higher oil pressure than that during the oil level measurement will cause the measurement to cease at 15-20ish%. Interestingly enough Ive also found that oil weight has no effect to the oil pressure (well at least between 5w-30 and 0w-20) which makes sense because it’s a variable displacement pump, the more fluid it displaces the higher the pressure.

What are normal parameters for oil pressure.

Mine is hovering around 60ish psi for the most part.

During oil measurement it should be 42-45psi

I'm at 45...seems pretty accurate -

So if I had to guess that means you shouldn’t have any problems measuring the oil level?

Correct, also I have a 2020 M340 04/19 production so most likely with the plastic oil pump

[JacobM340i]

I can only measure my oil level when my car cools down, when my car is cool and I measure the oil level, oil pressure bounce between 42-45psi and it goes all the way to 100% and gives me the level. When the car is hot, oil pressure when measuring bounce between 45-48psi and it fails at 20%. Im not engineer so I’m not sure as to why the pump puts out more volume/pressure when the oil/engine is warmer but that’s the way it is. Bmw has said with the n55 that the increase in pressure does not cause any damage.

On that note this whole issues could be fixed with a simple software update to make the system not so sensitive to oil pressure not sure why bmw hasn’t gone that route or maybe they are currently rewriting a new software update for this, idk…

Chance are as your pump ages more you won’t be able to measure anymore unfortunately, (well at least when engine is hot). At 45psi you are right at the cutoff of the computer failing the measurement. So am I though haha

You are right when hot it happened it doesn't read 🙄

But on the bright side the ultrasonic sensor mounted to the oil pan should still be functioning just fine and will tell you when your oil is below minimum and to “add 1 quart immediately”. However when I get to the point when I can’t read the oil level at all hot or cold I’ll probably change the pump just so I know the exact amount of oil in the engine for oil changes and stuff and making sure it’s not over filled.

How can I check the pressure of the pump?

And which build dates are affected by the bad oil pumps?

You can check using Bimmerlink
It's been posted around which years... But something like build before 09/20... (wild guess here)

[Marc R]

Not possible with bimmercode?

Different purposes, just get bimmerlink it's useful.

I have a 03/19 build date and I’m at 30,500 miles, my warranty ran out 2 months ago. How worried should I be my car reads oil fine do you guys think I should just wait til it breaks or change it immediately? have people actually lost an engine due to the oil pump failure?

As long as you have the brake/vaccum recall done you don’t have to worry about ur engine going kaboom unless your oil pressures looking funky.

Folks lost engines not because of an oil pump failure but a software issue where during certain start scenarios the engine would crank backwards cracking the oil pump and engine would go roast within the next few starts.

I have a 2020 with a build date of 4/29/19.
I dont have the cooling performance package (which was assumed to be accompanied by the more robust all metal oil pump) but just checked with bmw parts and my vin actually came with the newer oil pump(part# 11-41-9-895-359).

Regardless, I have never been able to measure my oil under any circumstance and i believe I’m starting to hear that same whine CrownRoyal79 was hearing from his oil pump. In January, during a morning startup, i received two codes for high oil pressure that tripped the CEL.

1C0101: Engine oil pressure control, plausibility, static: pressure too high
1C2001: Engine oil pump: pressure too high
(Bimmerlink)

The codes have not shown up again and the car has been running fine apart from a random EWS pinion starter error.

Going to get the recall done asap!

But im worried now!

Post a video of the whine, also when u call the dealer all they do is look up the part number for your vehicle, which is the latest revision because it superseded the old one, I can almost guarantee you that u have the old style pump.

I was thinking that exactly and asked again if it was specific to my vin number and not just the part # that comes up with the vehicle model now because that’s the revised version and he said it was specific to my vin. 🤷🏾‍♂️ it’s probably the old one smh

I tried to capture the whine a couple times but im not sure how clear it comes through on video. I’ll post it up

[MAKH 5]

This is the whine…

How can one check list of recalls that have been completed? When I search on BMW website it just shows that they were completed, not which ones though.

This is for a vehicle I am looking to purchase, build is 03/19 - it would give me peace of mind to see oil pump issue has been taken care of.
