Oil Sensor Fault?

Hello,

Has anyone ever had a failure of the oil level sensor?

I had a check oil fault 3 times on a recent 250KM drive back at high speeds. The first time, I checked the level and it was just as the MIN on the dipstick. Added 400 ml of oil. The second time it was again at the MIN level on the dipstick, added 600 ml of oil. The 3rd time it was also at MIN on the dipstick, and then I realized I should wait a moment for the oil in the engine to settle down. After 5 mins, I checked and the level rose to just above the scratched line on the dipstick. So I did not add any oil. The fault stayed on, but after I 30 mins when I was driving slower in an extended construction zone, it went off.

When I returned home, the oil level was the same, just above the scratched line. This is where it has been for the most part since I last changed the oil, 3700 miles ago.

Thoughts?
