Too much oil?

I had a warning pop up on my mini 1D saying I need to add oil imediatly. I wasn't the one driving the car arround for a while so I figured the warning had started to appear for a while now.

Did a measurement using the main console and the oil level was bellow minimum so I added 2L of oil. Now it shows the oil level is above the maximum (with a yellow warning).

What can I do? I've read that these digital tools of the 1D's and Coopers aren't trustworthy. I need to drive up to my family for christmas today but am scared of causing damage to my car.
