Evening all, car is a 2004, 1.6 petrol with 123k. Serviced 3 months ago, oil level is checked every week and hasn't dropped at all since. For the last 3 weeks however the yellow oil lamp has flashed on start up, for a few seconds, then goes off, never occurs when car is on the move, cold or hot, prob only 2/3 times a week at the moment. The handbook states low oil, but this is clearly not the case. Any ideas what this could be, or the start of being? Thanks

faulty sensor?

Is the car parked on a hill?

Is the car parked on a hill?

No, in the drive, or at work, always on a level area
