Hello BMW-Biker, I have a warning (call sign) for oil on board computer for some time now. The display comes only when the engine is warm. The oil level is in the upper third. The engine temperature indicator in the valve is also in the green area. What does the onboard computer ask for? Oil level or oil temperature? Does the BC have an extra sensor or is it the same as for the analog display in the armature? I actually tap on a defective sensor. So the cooling circuit works. Oil level is, as I said, also correct. Who knows where to attack there.
