Hello guys.
Couple of weeks i bought BMW F10 with 2.0d 184ks.
When i bought it, i dont see a little issue. On cold start, first in the morning i got alert, STOP the car, engine oil pressure too low. After 3s the alert is gone. The engine is running well, no shaking, no noise. The car has 212k on clock. I dont have the history so i dont know what is changed what is not.
I had tried this :
- Change oil 5w-30 Castrol and filter
- Change oil case with coolers
- Put on diagnostic, not a one fault, everything is good.
- Before first crank, open the filter put 50ml oil and start the car, same situation
- Changed oil pressure sensor.
After the first start, i can start all day not even one alert is coming, the car is running perfect.

I went to 3 other workshops and they said common problem on this engine is the oil pump.
Any suggestion before change that, because is a expensive part 1k euro.

Thank you in advance.
