Engine fault code (1C0001) keep coming up?

BMWnation · 10-08-2022, 12:22 PM

Hi all, have no check engine light, but I decided to check codes with MHD app and noticed this code:

1C0001 - Oil-pressure control: Pressure variations.

This is the second time it has came up. Car works fine.

Anyone have any insights what the issue is?

Thanks

If I had to guess, oil pressure sensor or worse case an oil pump…

I had the same issue, It was a recall with my car with main bearing shell. I got a full motor replacement and took about 3 months at a dealership.

Thanks for the information. Good to know. The code came back up again after a long time.
Will have the dealer look into it. Looks like there is a possibility folks might be getting this code but unaware as it does not throw a check engine light. You have to ready your DME to get the codes

Forgot to ask, what year/build date is your car?
I’m 2022 with build date of JAN 22

update: one of the members told me this was related to moving the car while the engine was off. after he stopped doing that the code went away

i suspect that this is my case as well, as I am manual I often roll my car out of the garage down the driveway without turning on the ignition. I cleared the code and stopped rolling my car, and am now reading my codes once a week so far it hasn't popped up again

In my case it was a bad oil pressure sensor... At 1800 miles.

Code came up again I will take to dealer

Is that to sneak out for a drive without anyone knowing you’ve left?

no, mainly for washing my car in the driveway without needing to wake up the whole neighborhood

Dealer diagnosed failing engine oil pump

Back ordered part for 3 weeks and then entire engine will need to be pulled apart 20 hour job

Demand a new engine, I wouldn’t feel comfortable knowing that damage might have already occurred.
