But then when I turn the car off and on again, it's gone.
When I purchased it and got the error, I did an oil & filter change, replaced the pressure sensor with an original one, put an oil additive (Bardahl's full metal) and it was all cool for around 2k km until the error started popping up again. Now, last week I changed my oil and filter again, put the same oil additive, but started getting the error on the next day. So I drove back to the BMW dealership, and they gave me an export from their system/diagnostics, which showed the error isn't due to a mechanical problem, but due to a software problem. So, they advised me to perform a software update of the car in their service and most likely (fingers crossed ��) the error will be gone. They told me my software is from 2014, so this issue is highly likely to be resolved in the later software versions. I have an appointment for the update due in 2 weeks, so I'll update you whether that has solved it for me.

Thanks for the reply. I did not update the thread after I fixed the problem, since there were no replies.
In a nutshell , I also replace the pressure sensor and replaced the oil. Than the error was only showing after I run ISTA check, but on the iDrive there were no more notifications. Part of the solution (at the time) was that the guys that changed my oil overfilled it with a 100-200 ml. Which I assume created more oil pressure within the system.
At the end, I've replaced the entire oil pump assembly (pump, pressure valve, chain) and that irradiated the issue completely. Most likely (unfortunately) that might be the problem. I was told that that's a common problem on Mini.
Best of luck to u!
