If I drive a distance of approx. 30-40 min, no matter whether highway or country road or through a town,

at some point (usually at a red light when I'm idle) the symbol comes with the red oil can. If I turn the car off and then on again, the problem is gone, but then the light comes back after about 10 minutes or only after 30 minutes, which is strange again.

The reading showed that the oil pressure was too low.

We have already replaced the oil sensor, we have replaced the oil pressure valve, the oil has been changed,

Oil filter was renewed, the oil was refilled and changed (of course the right oil), the oil pressure was measured and was also okay ... I am overwhelmed.

Maybe someone can help me or has other tips / solutions?

Drive to the BMW dealer and have the real oil pressure (on the oil filter housing) measured. Then you have clarity.

Did you sort this problem I have the same?

I had the same problem with mine last year, and it happened again.

So, everything you can possibly think of was changed. I even changed the oil pump, and once I did, the problem disappeared. Up until now.

It happened again, the red oil light popped up after 30-40 mins of driving. I have a weird theory that it comes with the temperature drop, but that's just a rookie guessing.

I also noticed that my oil level dropped, and it's in between min and max scale, so that might be the reason for the low oil pressure.

Anyone has any idea what this actually might be?

Im a car trader and 7/10 bmw 1 series that i collect has this issue its normally when the engines warmed up and the oil pressure light comes up after 30 mins of driving ive found that its always the 2litre petrol and the problem is normally because of the oil level sensor or the  oil filter housing.

hey guys I'm literally having the very same issue. bmw 120i m sport 2.0 2009 I drive for a little bit then the oil light suddenly appears. switch the car off and it's away.
I'm literally desperate I took it to a mechanic a month ago and the car kept leaving the garage with the problem still there. I feel like the mechanic genuinely took advantage of me, changed the oil cup, cam belt and bushings with no success. the red oil light is still there and i now have to travel back to the uk from italy with the constant worry that the car will die on me in the middle of the trip.
can someone please give me some light

Guys I just said to myself - screw the car, if it dies, it dies. The red light is still poppin' like crazy, but it's been like that for a full year now. I'm so used to it and I don't really care.
